Streszczenie:
Despite the fact that many research have been carried out on the characterization of the effects of whole-body vibration on seated occupants’ comfort, there is still very little scientific knowledge regarding drowsiness caused by the vibrations. Furthermore, there are less verified measurement methods available to quantify the whole body vibration-induced drowsiness of the vehicle occupants. This study is therefore set out to evaluate the effect of vibrations on drowsiness. 20 male volunteers have been recruited for this experiment. The data for this study is gathered from 10-minute simulated driving sessions under both no-vibration conditions and with a vibration that is randomly organized. Gaussian random vibration, with 1-15 Hz frequency bandwidth at 0.2 ms-2 r.m.s. for 30 minutes, is applied. During the driving session, the volunteers are required to obey the speed limit of a 100 kph and keep a consistent position in the left-hand lane. The deviation in the lateral position are recorded and analyzed. Additionally, the volunteers are also asked to rate their subjective drowsiness level by means of Karolinska Sleepiness Scale (KSS) scores for every five minutes. Based on the results, the role of vibration in promoting drowsiness can be observed from the driving impairment following 30-mins exposure to vibration.

Whole body vibration (WBV) platforms are currently used for muscle training and rehabilitation. However, the effectiveness of WBV training remains elusive, since scientific studies vary largely in the vibration parameters used. The origin of this issue may be related to a lack in understanding of the training intensity that is imposed on individual muscles by WBV. Therefore, this study evaluates the training intensity in terms of metabolic rate of two lower-extremity muscles during WBV under different vibration parameters. Fourteen healthy male subjects were randomly exposed to 0 (control)-, 10-, 17-, and 28-Hz vibrations while standing upright on a vibration platform. A near-infrared spectrometer was used to determine the gastrocnemius medialis (GM) and vastus lateralis (VL) muscles' metabolic rates during arterial occlusion. The metabolic rates during each vibration condition were significantly higher compared with control for both muscles ( P < 0.05). Each increase in vibration frequency translated into a significantly higher metabolic rate than the previous lower frequency ( P < 0.05) for both muscles. The current study showed that the local metabolic rate during WBV at 28 Hz was on average 5.4 times (GM) and 3.7 times (VL) of the control metabolic rate. The substantial changes in local metabolic rate indicate that WBV may represent a significant local training stimulus for particular leg muscles.

Purposes of the study were to measure mechanical vibrations transmitted to train operators, to calculate daily whole-body vibration exposure levels, to compare measured levels with maximum acceptable exposure levels according to the international standard on whole-body vibration, to identify factors that influence vibration levels, and to quantify the effects of these factors on the measured levels. As a result of this study, it was determined that six out of twenty subway lines had vibration levels higher than the daily exposure limits recommended by the international standard, and that train speed was the most significant factor influencing the vibration levels.

The objective of the study is to measure the whole body vibration (WBV) transmitted to the driver as well as the passengers during the operation of bus and to compare results with ISO 2631-1(1997) comfort chart and health guidance criteria. In this study, vibration exposure of the driver, passenger in the mid row seat and passenger in the rear row seat were measured at different operating conditions (static and dynamic). The BMI (Body Mass Index) was maintained for driver and passengers. The results of static test showed that the driver seat produced more vibrations compared to the passenger's mid row and rear row seat. This is due to the fact that driver seat was positioned close to the engine cabin. The results of dynamic test showed that, in all cases, the rear seat produced maximum vibrations. At 40 km/h speed the vibration magnitude exceeded the exposure limit at all tested seats. This high vibration magnitude might be due to the resonance effect caused between engine and chassis vibrations.

Vibrations are all around us. We can detect vibrations with sensitive skin mechanoreceptors, but our conscious awareness of the presence of vibrations is often limited. Nevertheless, vibrations play a role in our everyday life. Here, we briefly describe the function of vibration detection and how it can be used for medical applications by way of whole body vibration. Strong vibrations can be harmful, but milder vibrations can be beneficial, although to what extent and how large the clinical relevance is are still controversial. Whole body vibration can be applied via a vibrating platform, used in both animal and human research. Recent findings make clear that the mode of action is twofold: next to the rather well-known exercise (muscle) component, it also has a sensory (skin) component. Notably, the sensory (skin) component stimulating the brain has potential for several purposes including improvements in brain-related disorders. Combining these two components by selecting the optimal settings in whole body vibration has clear potential for medical applications. To realize this, the field needs more standardized and personalized protocols. It should tackle what could be considered the “Big Five” variables of whole body vibration designs: vibration amplitude, vibration frequency, method of application, session duration/frequency, and total intervention duration. Unraveling the underlying mechanisms by translational research can help to determine the optimal settings. Many systematic reviews on whole body vibration end with the conclusion that the findings are promising yet inconclusive. This is mainly because of the large variation in the “Big Five” settings between studies and incomplete reporting of methodological details hindering reproducibility. We are of the opinion that when (part of) these optimal settings are being realized, a much better estimate can be given about the true potential of whole body vibration as a medical application.

Streszczenie:
Obiettivo di questa tesi è la determinazione e quantificazione degli effetti della whole-body vibration al corpo umano, in termini di consumo energetico, tramite un approccio globale e integrato. L’obiettivo è ottenuto considerando il corpo umano come una struttura organica complessa. Allo scopo di comprendere come questo risponda alle vibrazioni verticali, il consumo energetico del corpo umano è stato misurato per mezzo della variazione della temperatura superficiale con tecniche di misurazione a termografia infrarossa. Lo spostamento dei muscoli invece con il sistema di analisi di movimento Vicon MX. Infine, per quanto riguarda il consumo di ossigeno con il sistema telemetrico Cosmed K4. Il primo passo è stato l’istituzione di un protocollo appropriato che soddisfi l’obiettivo di questo studio. Infatti, la mancanza di coerenza nei protocollo di whole-body vibration che si trovano allo stato dell’arte, ha reso essenziale l’istituzione di un apposito protocollo, ed a questo scopo è stata definita la struttura dell’esperimento. Di conseguenza, è stata avviata una serie di prove per esaminare la risposta del corpo umano alle vibrazioni verticali, cambiando la durata e la frequenza della vibrazione, nonché la durata del periodo di riposo. In totale, quattro persone in piedi sono state sottoposte a vibrazioni verticali, in una pedana vibrante, a frequenze da 20 a 50 Hz. Dopo l’instaurazione del protocollo finale, sono stati avviate una serie di prove di laboratorio. In particolare, sono state scelte tre frequenze per le vibrazioni: 20, 30 e 45 Hz. I risultati ottenuti più interessanti di questo studio, riguardano il consumo di ossigeno, la temperatura superficiale e i coefficienti di trasmissibilità dell’accelerazione.
The objective of this thesis is to determine and quantify the effects of whole-body vibration to the human body in terms of energy expenditure, by means of a global and integrated approach. This objective is attained by considering the human body as a complex organic structure. In order to understand how it responds to vertical vibrations, the energy expenditure of the human body was measured by means of the variation in superficial temperature with the aid of infrared thermography, the displacement of the muscles with the aid of the Vicon MX motion analysis system and the oxygen uptake with the aid of the Cosmed K4 telemetric system. The establishment of an appropriate protocol which satisfies the aim of this study was the first goal. The lack of consistency in whole-body vibration protocols in the current published studies makes the establishment of an appropriate protocol essential, and in this sense, an experiment setup was implemented. Therefore, a series of experiments was conducted to examine the response of the human body to vertical vibrations, changing the duration and the frequency of vertical vibration, and the duration of rest period. A number of four persons were subjected to vertical vibrations on a vibrating table in a standing position at a frequency ranging from 20 to 50 Hz. After the establishment of the final protocol, a series of laboratory experiments took place. Three different vibration frequencies were chosen: 20, 30 and 45 Hz corresponding to three different tests. The most interesting findings regard the oxygen consumption, the superficial temperature evolution, and the transmissibility coefficients for the acceleration.

Whole-body vibration (WBV) has been identified as a stressor to supine patients with head and spinal injuries during medical transportation. Limited information is available on the dynamic effects of the long spinal board and stretcher in vibrating environments. This is the first study to investigate the transmission of vibration through the long spinal board, military stretcher, and supine human in relation to a control case with full-rigid support. A sample of eight healthy male participants was used in this study. Each was placed on a vibration platform using spinal immobilization. Random vibration was applied in the fore-aft, lateral, and vertical directions, and the transmission of vibration was computed for the head, sternum, and pelvis. In addition, a novel approach to assess relative motion between segments, called relative transmissibility, was introduced. Compared to full-rigid support, the long spinal board strapped to a standard military litter system showed a 50% increase in transmission of anterior-posterior vibration to the head and a 100% increase to the sternum at its resonance frequency of 5 Hz (p < 0.05, Wilcoxon) for vertical vibration. Use of the cervical collar during immobilization increased the head nodding and the relative head-sternum flexion-extension as a result of the input fore-aft (axial) whole-body vibration. Yet, head nodding was reduced from vertical (anterior-posterior) input vibration. Relative transmissibility has revealed that at 5 Hz, the acceleration difference between the head and sternum was 1.5 times the vertical (anterior-posterior) input acceleration using the spinal board upon the military litter. During air, ground, and hand transportation, WBV may occur around 5 Hz. Patients with head and spinal cord injuries may benefit from vibration-suppression designs that minimize (1) the overall transmission of vibration in each axis and (2) the relative accelerations between segments for the most common vibration frequencies that occur during transportation. Furthermore, vibration applied in each axis independently showed transmissibility results comparable to that of simultaneous stimuli in three axes. Although the effects of vibration are quantified in this study, transient shock type vibration should be investigated and future research should be done to fully understand the clinical significance and application of these results.

Vibrations are often experienced in the workplace and may influence performance and executive function. Research has shown that vibrations may have an affect effect on drowsiness and tests related to inhibitory control. Previous work investigating whole body vibrations (WBV) and their effect was evaluated to inform the decisions for this study. WBV effects on cognitive abilities were examined and the different tests used in these studies were identified and compared. Electroencephalogram (EEG) and event related potentials (ERP) were selected to be used to measure inhibitory and cognitive processes. The N2 ERP, which reflects inhibitory control processes, was examined as well as the dominant frequency of the Fourier fast transform (FFT). A total of 94 participants between the ages of 18-55 (Mage = 20.49 SDage = 1.68) completed this study (51 female, 38 male and 5 with no gender listed). A go/no-go task was used to elicit the N2 ERP after WBV and a simultaneous EEG recording while the participants experienced WBV was used to gather the needed data. Stimulus frequencies used for the N2 ERP included 15 Hz, 20 Hz, and 40 Hz. During the simultaneous recording stimulus frequency varied every 30 seconds by 10 Hz from 20 Hz to 110 Hz. Data were analyzed using both a linear mixed effects model for normally distributed data and a generalized linear mixed effects model for data taken as percentages. It was hypothesized that there would be an effect on performance as measured in the raw go/no-go results, that this change in performance showing improved accuracy would be linked to inhibitory control, and be seen as a decrease in the magnitude of the N2 ERP. It was also hypothesized that the exploratory FFT portion of the study would produce a shift from a higher to a lower frequency in the dominant waveform . The results show that there were no main effects in either the behavioral performance or in the N2 ERP of the participants but that there was a significant interaction at 40 Hz with improved simple go trial activity and decreased no-go inhibition. The results also show that there was a statistically significant shift in neural oscillation activity but that this shift was not real-world relevant within the context of this study.

Streszczenie:
Whole body vibration (WBV) delivers a stimulus to the body via an oscillating platform and remains a relatively new area of research. Several applications of WBV stimuli have been developed as strength training and rehabilitation modalities, but inconsistent results have been published. There is little knowledge underpinning the mechanisms to explain the elicited neuromuscular responses to WBV and a wide range of WBV parameters across the literature. As a result, safe and effective protocols are yet to be established or validated. The aim of this current research was to investigate: the electromyography (EMG) and explosive performance responses to varying WBV frequencies; the effect of WBV data analysis techniques; and the influence of external factors on WBV stimulus and neuromuscular responses. Three main studies were completed: 1. An individualised response of both EMG and jump performance appears to exist dependent on vertical WBV frequency, in trained participants. This is in spite of no overall frequency dependent effect of EMG or performance responses across participants as a group. The influence of the role of expectancy effect appears minimal following this particular WBV protocol. 2. There was a significant effect of filter technique on EMG data recorded during vertical WBV. A tailored, WBV specific notch filter technique may offer an effective balance; excluding WBV noise artifacts without removing significant portions of valuable muscle signal EMG data. 3. The influence of external load on WBV acceleration output also appears minimal. Platform acceleration output was dependent on WBV frequency, as expected. Lower accelerations were recorded in superior body segments, suggesting a dampening mechanism, which was also proportionally dependent on frequency. EMG activity of upper and lower leg segments may differ in response to frequency, likely due to transmission distances involved. This may partially account for a potential dampening mechanism. In addition, a protocol to quantify WBV stimuli delivered by this particular WBV type illustrated significant differences in theoretical and actual parameters. This may explain not only the lack of overall explosive performance effect reported earlier; but also the inconsistent WBV literature. Future research should quantify WBV stimulus before investigating possible neuromuscular responses to individualised protocols, which may be assessed via EMG activity.

Streszczenie:
Low back disorders and their prevention is of great importance for companies and their employees. Whole-body vibration is a risk factor for low back disorders, but the neuromuscular, biomechanical, and/or physiological mechanisms responsible for this increased risk are unclear. These studies investigated changes in the biomechanics and control of the trunk in order to further the understanding of the mechanisms responsible for this increased risk. The purpose of the first study was to measure the acute effect of seated whole-body vibration on the postural control of the trunk during unstable seated balance. The findings show that whole-body vibration impaired the postural control of the trunk as evidenced by increased kinematic variance and non-linear stability control measures during unstable sitting. These findings imply an impairment in spinal stability control. The purpose of the second study was to measure the effect of seated whole-body vibration on the parameters of spinal stability control: passive stiffness, active stiffness, and neuromuscular reflexes. The findings show that whole-body vibration altered trunk stiffness (passive stiffness and equivalent reflex stiffness) as well as reflex dynamics. There was no evidence of compensation by active muscle co-contraction recruitment for the decreased trunk stiffness and reflex gain. The purpose of the third study was to measure the changes in the natural frequency characteristics of the trunk (which can be related to trunk stiffness and damping) during exposure to seated whole-body vibration. The findings show that whole-body vibration caused a decrease in natural frequency suggesting a decrease in the trunk stiffness, and also an increase in the peak amplitude of the frequency response functions suggesting a decrease in overall trunk damping. The rate of change of the natural frequency characteristics suggest that the majority of effects happen within the first 10 minutes of vibration exposure. These findings reveal changes in the biomechanical properties of the trunk with exposure to seated whole body vibration, and a mechanism by which vibration may increase the risk of low back injury.

The aim of the study was to determine and document evidence of the comparative effect of a 12- week whole body vibration training programme, exercise training programme and sedentary control group on the anthropometric profile, aerobic capacity, lung volumes and hence, the pulmonary capacity in people with asthma. The study used a descriptive, exploratory, quasi-experimental research approach employing randomised pairing to classify participants into either the whole body vibration therapy or exercise training group. Accidental and snowball sampling was used to identify and obtain a base of volunteers. A three-group pre-test/post-test design was employed to gain insight into statistical differences that might be apparent between the whole body vibration therapy group, the exercise group and the control group, and which could potentially be attributed to participation in the whole body vibration exercise programme. Randomised pairing for participant selection was selected because of the potential effects varying pulmonary variables might have had on the reliability of the study. A Physical Activity Selection Criteria Questionnaire was completed by participants to ascertain baseline physical activity readiness and as a means of determining selection criteria for their allocation to the whole body vibration training group, the experimental exercise group or the true control group. The pre-test/post-test assessment made use of a combination evaluation that incorporated an anthropometric profile assessment of height, weight, biceps, triceps, subscapular and suprailliac skinfolds, waist and hip circumference and posture, an aerobic capacity evaluation that incorporated aspects of both the YMCA and Astrand and Rhyming Physical Work Capacity (PWC) evaluation on a cycle ergometer and, lastly, a pulmonary variable assessment that made use of both the Datospir Peak-10 peak flow meter and the Spirovit SP-100AT spirometry unit integrated into the Cardiovit AT-6 model for all spirometry measurements. Participants were required to complete either the whole-body vibration or the exercise training programme a minimum of twice a week and a maximum of four times over the same period. The duration of the intervention programmes was approximately 30 minutes and consisted of three sections including a warm-up comprising flexibility exercises, whole body strength training exercises, and a cool-down which, in turn, consisted of massage exercises or replicated flexibility exercises. The main difference between the whole body vibration and exercise training group thus lay in the exclusion of the use of vibration for those participants assigned to the exercise training programme. Analysis of data was performed using descriptive and inferential statistics with the help of a qualified statistician. The identified variables were tested at a 95 percent level of probability (p<0.05) as recommended by Thomas and Nelson (1996:117). Descriptive data, in the form of a statistical mean, standard deviation, minimum, median and maximum values, obtained during this study were reported in the form of a t-score for selected anthropometric and pulmonary variables. The 12-week intervention programme, on analysis of the results, produced statistically insignificant improvements in the variables of anthropometric profile, aerobic capacity and lung volumes identified as determinants of, and factors influencing, the cardiorespiratory fitness level of participants with asthma and hence, the subsequent severity of this chronic condition. However, slight mean increases for the whole body vibration training group were evident for certain variables identified in this study. Based on the results, the inference could be made that whole body vibration therapy and exercise were both effective modes of training to improve the cardiorespiratory fitness level of people with asthma, but the results of the study did not show sufficient practical or statistical significance to verify the assumption that whole body vibration training was a method superior to conventional exercise training. Hence, the significance of whole body vibration training on the pulmonary variables of people with asthma could not be determined. The researcher recommends that future studies be undertaken to verify whether whole body vibration training incorporating larger participant groups could produce significant improvements in pulmonary variables in people with asthma.

Streszczenie:
Exposure to acute bouts of whole body vibration (WBV), which can be employed as a novel form of exercise, has been reported to increase local skeletal muscle blood flow. However, the mechanism for this effect remains unclear. Therefore, this research aimed to explore the mechanism that would explain the effect of vibration on the peripheral cardiovascular function. Initially, the aim was to investigate the potential mechanism of the effect of WBV on the systemic blood flow, since there are currently no studies reporting any systemic effects of WBV on blood flow. The results did not demonstrate any systemic effects on blood flow (i.e. forearm blood flow) in response to acute unloaded and loaded squats with WBV. It was concluded that it was difficult to identify the effects of vibration on systemic cardiovascular function because, most likely due to the higher exercise intensity, skeletal muscle activation resulted in a decrement in blood flow from a distal site (i.e. forearm) to the main site (i.e. lower limb). Through the development of experimental methods involving applying vibration passively to the lower limbs, which avoids any influence of direct skeletal muscle activation and focuses solely on the mechanism inducing effects, it was demonstrated that ankle systolic blood pressure and ankle brachial pressure index substantially decreased in the post-vibration period. It was concluded that vibration has a direct effect on the peripheral cardiovascular function via increased vasodilatation; however, the mechanism underlying this effect remained unresolved. The effects of different durations of passive vibration on the peripheral circulation were also investigated and the results demonstrated that a longer duration of passive vibration (i.e. 8 minutes) resulted in a significantly higher lower leg blood flow during the recovery period than a shorter duration (i.e. 1, 2 and 4 minutes) of passive vibration. These data provide evidence for a greater effect of WBV occurring with a longer duration on the peripheral cardiovascular function, caused by the vasodilatation response throughout the recovery period. However, there might be a minimum effect of skeletal muscle activation occurring with a longer duration of passive vibration that leads to a direct response to localised heating. Furthermore, the thesis attempted to distinguish the effects of passive vibration on skeletal muscle activation from those on the peripheral vascular system. An experiment was designed in which passive vibration was applied with and without circulatory occlusion, to examine whether there was any underlying skeletal muscle activation. It was found that vibration with intact circulation produces more heat than the control, no vibration and occlusion, and occlusion plus vibration conditions. These effects were reflected by the higher skin temperature observed during exposure to vibration, and continuing into recovery. These data provide evidence that passive vibration does not appear to induce an increase in muscle activity. The data also suggest that the mechanism of the rise in skin temperature in response to passive vibration exposure is due to a vasodilatation that occurred in the lower limb via inducing an increase in shear stress at the blood vessels wall and led to an increase in circulating blood flow during exposure that continues into recovery. Overall, the results obtained demonstrate that vasodilatation occurs during and after vibration exposure and appears to be a process that is independent of skeletal muscle activation. It is postulated that the stimulus is a direct effect on the blood vessels via inducing an increase in shear stress that results in an increased vasodilatation, thereby increasing blood flow. Hence, these observations demonstrate that vibration stimulus has a direct effect on the muscle vascular bed as a primary effect and that there is no carry over effect into the systemic circulation. Thus, the results of this thesis indicate that vibration induced enhancement in the peripheral circulation could be using as a training stimulus and also could have a beneficial effect in assisting recovery routines from exertion.

Streszczenie:
Locomotives produce vibrations and mechanical shocks from irregularities in the track, structural dynamics, the engines, the trucks, and train slack movement (Mansfield, 2005). The different directions of the irregularities give rise to car-body vibrations in multiple axes including the following: • Longitudinal, or along the length of the train (x); • Lateral, or the side-to-side direction of the train (y); • Vertical (z). Some reports suggest that acceleration at the seat pan is greater than that at the floor, indicating that the seat may amplify the vibration (Johanning, et al., 2006; Mansfield, 2005; Oborne & Clarke, 1974; Transport, 1980). The magnitude of vertical vibration in rail vehicles is reportedly well below many other types of vehicles (Dupuis & Zerlett, 1986; Griffin, 1990; Johanning, 1998). However, some research reports that rail vehicles experience far more lateral vibratory motion than cars and trucks (Lundstrom & Lindberg, 1983). Many factors influence the impact of shock felt by the engineer including train speed, consist, engineer control skills, anticipation of the shock, motion amplitude, shock duration, and body posture. Shock events and vibration affect ride quality; however, shocks are less controllable by locomotive design. Common sources of mechanical shock are coupling and slack run-ins and run-outs (Multer, et al., 1998). While there are investigations of whole-body vibration (WBV) in locomotive cabs reported in the literature, there have been no studies to date that have examined long-haul continuous vibrations (> 16 hr). The authors describe a long-haul WBV study collected on a 2007 GE ES44DC locomotive. It is the first in a series of studies sponsored by the Federal Railroad Administration (FRA) to examine WBV and shock in locomotive cabs. The researchers recorded vibration data using 2 triaxial accelerometers on the engineers’ seat: a seat pad accelerometer placed on the seat cushion and a frame accelerometer attached to the seat frame at the base. Data collection occurred over 550 track miles for 16hr 44min. ISO 2631-1 defines methods for the measurement of periodic, random and transient WBV. The focus of ISO 2631-5 is to evaluate the exposure of a seated person to multiple mechanical shocks from seat pad measurements. The research team collected and analyzed vibrations in accordance with ISO 2631-1 and ISO 2631-5. The results from the study as well as future planned long-haul studies will provide a benchmark set of WBV metrics that define the vibration environment of present-day locomotive operations.

Streszczenie:
Low back disorders are very common affecting up to 80% of the population in their lifetime [1]. Whole body vibration (WBV) exposure has long been identified as an important risk factor for low back disorders in industrial workers [2]. A potential mechanism has been proposed by which vibration may lead to injury. Namely, vibration-induced losses in proprioception may lead to inappropriate stabilization and poor dynamic control of the lumbar spine [3]. Increases in proprioceptive errors and in delays in neuormotor response have been demonstrated with 5 Hz, vertical seatpan vibration [3]. While vertical vibration exposure is a common occupational exposure, in some cases, such as off road vehicles and construction vehicles horizontal (fore-aft) vibration may dominate [4]. In this study, the objective was to investigate how the whole body, horizontal, seatpan vibration affects muscle response and to compare these results with the previously studied whole body vertical vibration.

Streszczenie:
Whole-body vibrations are an integral part of daily life experience. A thorough understanding of human vibration perception is necessary, e.g., for both the design of multi-modal virtual environments as well as the evaluation of comfort in the automotive industry. In this study, intensity perception for whole-body vibrations near threshold has been measured using amplitude modulated signals as well as narrow band noises. Stevens’ exponents have been calculated showing a significant dependence on frequency between 31.5 Hz and 125 Hz with higher frequencies leading to lower Stevens’ exponents. Amplitude modulation does not have an effect on intensity perception. The use of narrow band noise leads to bigger differences among Stevens’ exponents compared to those of sinusoidal signals. It is concluded that perceptual data from experiments with sinusoidal signals can be used to model the intensity perception of modulated signals, but adjustments have to be made for noisy signals.

Streszczenie:
Locomotives produce vibrations and mechanical shocks from irregularities in the track, structural dynamics, the engines, the trucks, and train slack movement (Mansfield, 2005). The different directions of the irregularities give rise to car-body vibrations in multiple axes including the following: • longitudinal, or along the length of the train (x); • lateral, or the side-to-side direction of the train (y); • vertical (z). The structural dynamics of rail vehicles give rise to several resonances in the 0.5–20Hz frequency range (Andersson, et al., 2005). Resonances are frequencies in the locomotive that cause larger amplitude oscillations. At these frequencies, even small-amplitude input vibration can produce large output oscillations. Further exacerbating the vibration environment, coupling of the axes of movement occurs: Motions in one direction contribute to motion in a different direction. The magnitude of vertical vibration in rail vehicles is reportedly well below many other types of vehicles (Dupuis & Zerlett, 1986; Griffin, 1990; Johanning, 1998). However, a lack of data from long-haul freight operations prevents an adequate characterization of the vibration environment of locomotive cabs. The authors describe results from 2 long-haul whole-body vibration (WBV) studies collected on a 2009 GE ES44C4 locomotive and a 2008 EMD SD70ACe. These WBV studies sponsored by the Federal Railroad Administration (FRA) examined WBV and shock in locomotives over 123 hours and 2274 track miles. The researchers recorded vibration data using 2 triaxial accelerometers on the engineers’ seat: a seat pad accelerometer placed on the seat cushion and a frame accelerometer attached to the seat frame at the base. The research team collected and analyzed vibrations in accordance with ISO 2631-1 and ISO 2631-5. ISO 2631-1 defines methods for the measurement of periodic, random and transient WBV. The focus of ISO 2631-5 is to evaluate the exposure of a seated person to multiple mechanical shocks from seat pad measurements. Exposure to excessive vibration is associated with an increased occupational risk of fatigue-related musculoskeletal injury and disruption of the vestibular system. While this is not an established causal relationship, it is possible that vibration approaching the ISO 2631-1 health caution guidance zones may lead to an increased occupational risk. The results from these rides show that the frequency-weighted ISO 2631 metrics are below the established health guidance caution zones of the WBV ISO 2631 standards. The goals of these studies are to: • collect data in accordance with international standards so results can be compared with similar findings in the literature for shorter duration rides as well as vibration studies in other transportation modes, • to characterize vibration and shock in a representative sample of locomotive operations to be able to generalize the results across the industry, and • collect benchmark data for future locomotive cab ride-quality standards.
