Abstract:

solidification, process shortening and energy saving. A twin-wheel caster equipped with two additional horizontal wheels was proposed to cast thin aluminum alloy wire at higher speed. In the proposed twin-wheel caster, a groove was machined on the lower wheel. Two small horizontal wheels were positioned between the molten-metal-pouring launder and the upper wheel to assist the solidification of poured molten metal and to prevent burr formation. The alignment of the horizontal wheel sensitively affected the occurrence of wire defects. An Al-1.2%Fe wire with a cross section of 6.2 mm2 was cast at 15 m/min. Thinner wires without burring could be cast at a speed higher than that of the twin-wheel caster without the horizontal wheels. The surface condition of the as-cast wire cast by the twin-wheel caster equipped with horizontal wheels was worse than that of the casting using the twin-wheel caster without horizontal wheels.

Abstract:

This paper aims to detect railway vehicle wheel flats and polygonized wheels using an envelope spectrum analysis. First, a brief explanation of railway vehicle wheel problems is presented, focusing particularly on wheel flats and polygonal wheels. Then, three types of wheel flat profiles and three periodic out-of-roundness (OOR) harmonic order ranges for the polygonal wheels are evaluated in the simulations, along with analyses implemented using only healthy wheels for comparison. Moreover, the simulation implements track irregularity profiles modelled based on the US Federal Railroad Administration (FRA). From the numerical calculations, the dynamic responses of several strain gauges (SGs) and accelerometer sensors located on the rail between sleepers are evaluated. Regarding defective wheels, only the right wheel of the first wheelset is considered as a defective wheel, but the detection methodology works for various damaged wheels located in any position. The results from the application of the methodology show that the envelope spectrum analysis successfully distinguishes a healthy wheel from a defective one.

Abstract:

Wheels have significant impact on noise and drag of road vehicles, which may influence their fuel consumption, emission and comfort. A number of studies have analyzed flow and aerodynamics of isolated wheel in contact with the ground, but limited attention has been given to interaction between wheels. The present study aims to compare the aerodynamics and flow structure between single and tandem wheels. To that end, flow around single and tandem wheels are simulated using a turbulence Scaled Adaptive Unsteady Reynolds Average Navier Stokes (URANS) model. Wheel geometry was based on the actual wheel used in the experiments of Fackrell and Harvey. Flow around single and tandem wheels were examined and compared, along with their respective drag and lift coefficients. Results for single wheel in contact with the ground show good agreement with previous experiments. In the tandem wheel case, the rear wheel exhibits lower drag coefficient (CD = 0.37) and more downforce (lift coefficient CL = -0.14) compared to the front wheel. The present investigation may help to illustrate impact of wheel interaction on their aerodynamics.

Abstract: Wheel rims are the most important part of automobile, in an automobile there are fatigue loads and static loads which are actively participated in design. There are several ways of failure of wheel rim like critical stresses and material failure due to design, dimension and shape of wheel also play vital role in its dimensions and shape vehicle rim design. Present paper studied the Y angle optimization in alloy wheel rim. The present design analysed by ANSYS software. For the structural analysis for the remote force the magnitude applied is 1000N and for the pressure which applied on the wheel is 245kPa. Therefore, so comparing the wheels with the total deformation occurred alloy wheels are better than the steel wheel and comparing the both the alloy wheels multi-spoke alloy wheel is better than the 6-spoke alloy wheel. The total deformation of 8 spoke alloy wheel with 55° Y spoke angle, figure clearly depicted the total deformation maximum value 0.00155mm maximum at base of wheel or outer periphery of wheel rim.

Abstract:

AbstractPolygonisation is a common nonuniform wear phenomenon occurring in railway vehicle wheels and has a severe impact on the vehicle–track system, ride comfort, and lineside residents. This paper first summarizes periodic defects of the wheels, including wheel polygonisation and wheel corrugation, occurring in railways worldwide. Thereafter, the effects of wheel polygonisation on the wheel–rail interaction, noise and vibration, and fatigue failure of the vehicle and track components are reviewed. Based on the different causes, the formation mechanisms of periodic wheel defects are classified into three categories: (1) initial defects of wheels, (2) natural vibration of the vehicle–track system, and (3) thermoelastic instability. In addition, the simulation methods of wheel polygonisation evolution and countermeasures to mitigate wheel polygonisation are presented. Emphasis is given to the characteristics, effects, causes, and solutions of wheel polygonisation in metro vehicles, locomotives, and high-speed trains in China. Finally, the guidance is provided on further understanding the formation mechanisms, monitoring technology, and maintenance criterion of wheel polygonisation.

Abstract:

Designing lightweight and comfortable automotive vehicles is a primary aim of the industry. Lightweight wheel designs can have a negative effect on the dynamic impact performance of the wheel; therefore, striking a balance between these two factors is a key objective in the design of automotive vehicles. Magnesium alloy wheels were investigated as magnesium alloy has damping performance advantages over some metal materials. Damping test methods were designed to establish the damping performance parameters of the magnesium alloy material. A finite element analysis model of magnesium alloy wheels was established with certain boundary conditions and constraints. The applicability of the model was verified by free modal evaluation of the wheel. Dynamic impact simulation analysis of the designed wheels was carried out, and the dynamic speed responses of magnesium alloy wheels under the impact of a dynamic load on the road surface were obtained. Comparison of the dynamic impact performance of magnesium and aluminum alloy wheels with the same structure showed that the magnesium alloy wheel achieved the target weight reduction of 32.3%; however, the dynamic impact performance was reduced. In order to realize the lightweight design, the dynamic impact performance of the magnesium alloy wheel should not be inferior to that of the aluminum alloy wheel; therefore, the design of the magnesium alloy wheel structure was optimized. The structural design optimization of the magnesium alloy wheel was carried out by defining the structural parameters of the wheel and using the acceleration and shock response of the wheel as the outputs. The optimization of weight reduction and dynamic impact performance of magnesium alloy wheels was achieved. Consequently, the designed magnesium alloy wheel was shown to have improved ride comfort while satisfying wheel structural performance standards and providing lightweight design.

Abstract:

These analysis ambitions to ascertain the major core cause of failures of rail wheels and to prevent the occurrence of same in future. One working model of train is developed to estimate the heat generated at brake pad-wheel and rail-wheel interfaces for locomotive and wagon wheels using the performance characteristics of brake blocks, the slip characteristics of wheel-rail traction and the resistance characteristics of a running train for given operating and braking conditions. The heat dissipation characteristics of rail-wheel and brake pad units interfaces in locomotive and wagon wheels and wheel running temperatures for different wheel profiles for different train running conditions are estimated. This work is carried out to identify the under-lying machinery of locomotive wheel failure due to widening and condemning of gauge. It has also accomplished the investigation on the impact of the type of brake block, wheel profile and braking conditions on locomotive wheel fiasco from gauge widening and condemning are also been carried out. It is suggested to use a high friction coefficient composite brake block results in higher wheel temperatures and cause large gauge changes, particularly for independent braking. Further, S-shaped wheels are found to be best suitable for avoiding undue gauge reduction or increase.

Abstract:

The majority of catastrophic wheel failures are caused by surface opening fatigue cracks either in the wheel tread or wheel flange areas. The inclined cracks at railway wheel tread are initiated and the cracks are caused by wheel damage-spalling after 60,000 km running. Because the failured railway wheel is reprofiled before regular wheel reprofiling, the maintenance cost for the railway wheel is increased. Therefore, it is necessary to analyze the mechanism for introduction of crack. In the present paper, the combined effect on railway wheels of a periodically varying contact pressure and an intermittent thermal braking loading is investigated. To analyze damage cause for railway wheels, the measurements for replica of wheel surface and effect of braking application in field test are carried out. The result shows that the surface cracks in railway wheel tread are due to combination of thermal loading and ratcheting.

Abstract:

Variable-diameter wheels balance the high mobility and limited volume of a planetary rover. Moreover, these wheels allow a rover to adjust its body attitude to adapt to rough terrains. These functions are achieved through the expansion–retraction motion of the variable-diameter mechanisms in the wheels. Thus, the traditional wheel design focuses on these mechanisms. To further facilitate its application, we propose a new concept variable-diameter wheel that considers the mechanism characteristics and wheel performances. This new wheel configuration is presented along with the corresponding transmission system, design, and analysis methods. Kinematic equations of the mechanism were established and then applied to synthesize the wheel dimensions. The load–deflection relationship of the wheels was analytically derived by developing a modified pseudo-rigid-body model (PRBM). Finite element analysis (FEA) simulations were performed to validate the design and analysis. In conclusion, the proposed novel wheel is extremely beneficial for rough-terrain locomotion systems. Furthermore, the design and analysis approaches used in this study are applicable for other expandable wheels.

Abstract:

Applied System Identification for a Four Wheel Reaction Wheel Platform By Seth Franklyn Silva At the California Polytechnic State University, San Luis Obispo there is a four-wheel reaction wheel pyramidal simulator platform supported by an air-bearing. This simulator has the current capability to measure the wheel speeds and angular velocity of the platform, and with these measurements, the system identification process was used to obtain the mass properties of this simulator. A handling algorithm was developed to allow wireless data acquisition and command to the spacecraft simulator from a “ground” computer allowing the simulator to be free of induced torques due to wiring. The system identification algorithm using a least squares estimation scheme was tested on this simulator and compared to theoretical analysis. The resultant principle inertia about the z-axis from the experimental analysis was 3.5 percent off the theoretical, while the other inertias had an error of up to 187 percent. The error is explained as noise attributed to noise in the measurement, averaging inconsistencies, low bandwidth, and derivation of accelerations from measured data.

Abstract:

This project is about building a three wheeled robot car with Omni wheels. Omni wheels can make a robot drive sideways without rotating first. They can make a robot rotate at the same time as it goes straight ahead. An Omni wheel robot can for example be good choice for a tracking robot, though it can drive more effective than a robot car with regular wheels. The thing that speaks against Omni wheels is that it has more friction and it takes more power to rotate the wheels. This robot car is an obstacles avoiding robot that should with help of Ultrasonic sensors and IR-sensors be able to drive around in a room without crashing in to objects or walls. With the help of Omni wheels the robot should drive without rotating much which makes it more effective than a robot car with regular wheels.
Det här projektet handlar om att bygga en trehjulig robotbil med Omnihjul. Omnihjul kan göra det möjligt för en robot att köra i sidled utan att först rotera. De kan också möjliggöra för en robot att rotera samtidigt som den kör rakt fram i en rak linje. En Omnihjulrobot kan till exempel vara ett bra val som spårningsrobot. För att den kan köra mer effektivt än en robotbil med vanliga hjul. Det som talar mot Omnihjul är att de har mer friktion och det krävs mer kraft för att rotera hjulen. Den här robotbilen är en hinderundvikande robot som med hjälp av Ultraljudssensorer och IR-sensorer ska kunna köra runt i ett rum utan att krasha in i objekt eller väggar. Med hjälp av Omnihjul ska roboten kunna köra utan att rotera mycket, vilket gör den mer effektiv än en robotbil med vanliga hjul.

Abstract:

The Pyramidal Reaction Wheel Platform, or PRWP, is used to simulate three-axis controls in a torque free space-like environment. The primary purpose of the system will be to evaluate the effects of conjoining sensors to maximize pointing accuracy. Furthermore, the system will incorporate a star tracker in conjunction with a Simulated Star Field (SSF) to better estimate the PRWP orientation. For the sake of this document, however, the goal is to implement a gyroscope, wheel rate sensors, and a make-shift accelerometer—to the PRWP—and integrate a controls algorithm such that three-axis controls are achieved for the PRWP. Three sensors were either better integrated into the system or added altogether. Tachometers were created as a form of hardware circuitry to measure each wheel rate with an accuracy of approximately 2.5 Hz (nearly 15 radians per second). The TAC board circuitry converted each motors encoder output into a speed by use of a frequency to voltage converter. Additionally, although three gyroscopes had been implemented previously, the system was better incorporated into the model such that it was directly transformed via a ROBOSTIX ADC converter before being relayed to SIMULINK via a Bluetooth link. The MEMS gyroscopes allowed for very accurate rate measurements—with a minimum resolution of approximately 0.25 radians per second. Finally, a makeshift accelerometer was incorporated into the system for the purpose of system identification. The accelerometer was incorporated into the system by utilizing a discrete time derivative of the gyroscope readings. However, thankfully a system of two accelerometers can be later utilized to achieve an accuracy of approximately 6 degrees per second-second in the x-axis and 2-3 degrees per second-second in the y- and z-axes. A controls test was performed where the starting location was qo=[0, 0, sqrt(2)/2, sqrt(2)/2] and the target location was qc=[0, 0, 0, 1]. At 80 seconds, the pointing accuracy was 70 degrees around the target and the system was unable to settle during the 80 second trial. The inaccuracy was because of the low frequency of operation of the system—1 Hz. Additionally, the platform reacts slowly to sensor readings and commands. The coupling of these issues causes the pointing accuracy to high. Furthermore, through experimental testing, the maximum wheel rate was found to be approximately 6400 RPM at a duty cycle of 50% at an 8000Hz PWM application due to the Pololu MD01B design limitations: low voltage range (up to 16V), low limit current limiter (5A), and high susceptibility to overheating for large currents.

Experiences with Spirit and Opportunity, the twin Mars Exploration Rovers, showed that one of the major issues that needs to be addressed in order to expand the exploration capabilities of planetary rovers is that of wheel traction. The relationships governing how much traction a wheel can produce are highly dependent on both the shape of the wheel and terrain properties. These relationships are complex and not yet fully understood. The amount of power required to drive a wheel is also dependent on its shape and the terrain properties. Wheel sizes that tend to maximize traction also tend to require more power. In the past, it has always been a challenge to find the right balance between designing a rover wheel with high traction capabilities and low power requirements. More recently, researchers invented the idea of a reconfigurable wheel which would have the ability to change its shape to adapt to the type of terrain it was on. In challenging terrain environments, the wheel could configure to a size that would maximize traction. In less challenging terrain environments, the wheel could configure to a size that would minimize power. Theoretical simulation showed that the use of reconfigurable wheels could improve tractive performance and some initial prototyping and experimental testing corroborated those findings. The purpose of this project was to extend that prototyping and experimenting. Four reconfigurable wheels were designed, built, and integrated onto an actual rover platform. A control methodology whereby the wheels could autonomously reconfigure was also designed, implemented, and demonstrated. The rover was then tested in a simulated Martian environment to assess the effectiveness of the reconfigurable wheels. During the tests, the power consumption and the distance traveled by the rover were both measured and recorded. In all tests, the wheels were able to successfully reconfigure and the rover continued to advance forward; but as was expected, the reconfigurable wheel system consumed more power than a non-reconfigurable wheel system. In the end, the results showed that if maximizing vehicle traction was weighed more heavily than minimizing power consumption, the use of reconfigurable wheels yielded a net gain in performance.

Abstract:

A general approach to numerically simulating wear in rollingand sliding contacts is presented in this thesis. A simulationscheme is developed that calculates the wear at a detailedlevel. The removal of material follows Archards wear law,which states that the reduction of volume is linearlyproportional to the sliding distance, the normal load and thewear coefficient. The target application is the wheel-railcontact.

Careful attention is paid to stress properties in the normaldirection of the contact. A Winkler method is used to calculatethe normal pressure. The model is calibrated either withresults from Finite Element simulations (which can include aplastic material model) or a linear-elastic contact model. Thetangential tractions and the sliding distances are calculatedusing a method that incorporates the effect of rigid bodymotion and tangential deformations in the contact zone.Kalkers Fastsim code is used to validate the tangentialcalculation method. Results of three different sorts ofexperiments (full-scale, pin-on-disc and disc-on-disc) wereused to establish the wear and friction coefficients underdifferent operating conditions.

The experimental results show that the sliding velocity andcontact pressure in the contact situation strongly influencethe wear coefficient. For the disc-on-disc simulation, therewas good agreement between experimental results and thesimulation in terms of wear and rolling friction underdifferent operating conditions. Good agreement was alsoobtained in regard to form change of the rollers. In thefull-scale simulations, a two-point contact was analysed wherethe differences between the contacts on rail-head to wheeltread and rail edge to wheel flange can be attributed primarilyto the relative velocity differences in regard to bothmagnitude and direction. Good qualitative agreement was foundbetween the simulated wear rate and the full-scale test resultsat different contact conditions.

The steering system of a rear wheel drive open wheel racecar is the only directional control the driver possesses while driving. Steering linkages must be carefully designed to allow cars to navigate turns without exhausting the driver. Motorsports vehicles are designed to make tight turns while maximizing tire grip to maintain higher velocities in corners. Steering geometry must be optimized not only for car performance, but also to maximize driver comfort and improve the "feel" of the vehicle. In competitive motorsports, the steering system is critical to vehicle performance: an incorrectly designed system can at best cost a few fractions of a second on the track, and at worst cause severe driver injury. In the Formula SAE competition, student teams are tasked with designing and manufacturing all subsystems of a racecar for an annual competition while balancing safety, cost, and performance. This thesis will introduce fundamentals of steering system design, and will document in detail the design, analysis, manufacture, and testing of the 2017 MIT FSAE steering system.

Abstract:

Recent x-ray diffraction testing of wheels with machined treads showed that axial residual stresses in the wheel rim were different than the axial residual stresses in Vertical Split Rim (VSR) wheels, and service worn wheels with no machining. As a result, a larger study was conducted at the wheel shops of major North American railroads. Tread damaged wheelsets were machined to remove tread damage and restore the flange/tread profile. The amount of metal removed from the treads was recorded, wheels were demounted, and slices were removed from the machined wheel rims at pre-marked areas for x-ray diffraction testing. The wheel rim axial residual stress patterns for the machined wheels are presented and are compared to the axial residual stress patterns for VSR wheels and used wheels with no machining. Data are presented for both forged and cast wheels. Implications for improved service performance from reduced tread damage are also discussed.

Abstract:

To improve railroad safety and efficiency, the Office of Research and Development of the Federal Railroad Administration (FRA) is running a project to develop and demonstrate an On-Board Monitoring Systems Concept (OBMSC) for freight trains. The project scope includes onboard detection of hot bearings, bearing defects, vehicle, ride quality, wheel tread defects, and derailed wheels. This paper presents an analytical model to detect derailed wheel conditions. In the model, an idealized wheelset with associated sprung and unsprung vehicle masses running on crossties is simulated using LS-Dyna software. Track structure (i.e., ties) ballast/subgrade, and soil are represented as linear elastic systems. This paper identifies wheelset vertical acceleration magnitude and associated frequencies for a derailed wheel for empty and loaded car conditions at various operating speeds. The research shows that the predicted wheelset acceleration magnitude for a derailed wheel overlap with those resulting from wheel tread defects, such as wheel flat, shells, and built-up tread. To differentiate between a derailed wheel and wheels with tread defects, a set of criteria is formulated based on amplitude and frequency ranges. Based on the analytical results from the derailed wheel model and field-tested results of revenue service wheels with tread defects, it is established that the OBMSC bearing adapter acceleration (BAA) can be used to detect a derailed wheel and conditions communicated to the train crew or other appropriate parties.

Abstract:

As transit vehicle wheels accrue mileage, they experience flange and tread wear based on the contact between the railhead and wheel-running surface. When wheels wear excessively, the likelihood of accidents and derailments increases. Thus, regular maintenance is performed on the wheels, until they require replacement. One common maintenance practice is truing; using a specially designed cutting machine to bring a wheel back to an acceptable profile. This process removes metal from the wheel and is often based on wheel flange thickness standards (and sometimes wheel flange angle). Wheel replacement is usually driven by rim thickness, which is continually reduced by wear and metal removed by truing. This research study used wheel wear data provided by the New York City Transit Authority (NYCTA) to analyze wheel wear trends and forecast wheel maintenance (truing based on flange thickness) and wheel life (replacement based on rim thickness). Using automatic wheel-scanning technology, NYCTA was able to collect wheel profile measurements for nearly 4,000 wheels in its fleet over a six-month period, measured weekly. The resulting wheel measurement data was analyzed using advanced stochastic techniques to determine relationships for the changes in flange thickness over time for each wheel in the fleet. Flange thickness wear rate relationships for each wheel were then used to forecast the time it would take for a wheel to reach the flange thickness maintenance threshold as defined by NYCTA standards. Furthermore, a subpopulation of wheels that exhibited very high rates of wear were classified as “bad actors” and identified for further investigation to understand the cause of accelerated wear. This allows for identification and addressing of causal factors that relate to accelerated wear, such as angle of attack and L/V ratio. NYCTA has recently started capturing such data that relates truck performance, which can be related to rate of wear.

Abstract:

To fine tune the aerodynamic properties of road going vehicles the flow along the underbody is of outmost importance. Hence moving ground facilities has been introduced. In full-width mono-belt facilities the test vehicle is most often suspended over the ground plane by a sting system. To mount the wheels, two possibilities exist. The designer of the wind tunnel model is faced with the choice to have the wheels on or off the model. The first option gives the most satisfying boundary conditions from a fluid dynamics point of view, however, the designer will face the problem of creating a frictionless chassis suspension system for the model. The “wheels off” type does not require such complex system but unfortunately creates a non-realistic flow due to the presence of so called wheel struts that carries the wheels. In the present work a numerical study of the flow around a “wheels off” model has been conducted. The study was performed to quantify how the presence of the wheel struts would affect the flow field and hence how this influence flow related measurements made on the model. The work has been done using a commercial CFD-code, running a standard k-epsilon model on a let-dominated mesh, counting roughly 6.5 million cells. As expected the flow field in the vicinity of the wheels is affected due to the extra vorticity introduced by the struts. The modified pressure field alters the drag and of further significance is the influence from the wheel struts on the underbody flow field. It is shown that care must be taken in studies of underbody and later underhood flows, using a “wheels-off” configuration.

Abstract:

Wheel dynamics is a significant component of vehicle dynamics and performance analysis. This paper presents an innovative method of studying wheel dynamics and wheel performance control based on the inverse dynamics formulation of the problem. Such an approach opens up a new way to the optimization and control of both vehicle dynamics and vehicle performance by optimizing and controlling power distribution to the drive wheels. An equation of motion of a wheel is derived first from the wheel power balance equation that makes the equation more general. This equation of motion is considered the basis for studying both direct and inverse wheel dynamics. The development of a control strategy on the basis of the inverse wheel dynamics approach includes wheel torque control that provides a wheel with both the referred angular velocity and rolling radius and also with the required functionals of quality. An algorithm for controlling the angular velocity is presented as the first part in the implementation of the developed strategy of the inverse wheel dynamics/performance control.

Abstract:

Abstract Among many testing items of infrastructure, wheel-rail force is an important factor that causes track failure, damage, train derailment and vehicle parts damage. It is also used to evaluate the ride stability, safety and as the main basis for speed limit and speed increase. Among many methods of wheel-rail force detection, the method of wheel-rail force measurement is the most accurate and direct method of wheel-rail force measurement. The method of measuring wheel-rail interaction force using wheelset of railway locomotive and rolling stock as force sensor has the highest accuracy among all wheel-rail force measurement methods. Force-measuring wheelset is the core sensor in the dynamic test research of railway vehicles, and its performance directly affects the evaluation results of the tested objects. Before the actual line test, it is necessary to calibrate the dynamometer wheelset on the test bench. The calibration of dynamometer wheelset is an important link in the research and application of dynamometer wheelset. With the rapid development of rail transit in various countries and the great improvement of locomotive and rolling stock manufacturing technology, higher and higher requirements has been put forward for the performance of force-measuring wheelsets, which are mainly embodied in obtaining ideal sensitivity and linearity, minimizing cross-interference and all kinds of possible external interference, and reducing the influence of the change of the position of the action point on the measurement results. For the rigid wheelset, the calibration of the force-measuring wheelset is basically perfect from the actual production to the algorithm. The relevant countries also determine the calibration in the standard form. At present, more and more urban rail low floor vehicles are using independent resilient wheels. The mechanical structure of the bogie with resilient wheels is complex. At the same time, because of the small diameter of the resilient wheels and the rubber layer between the wheel hoop and the wheel center, it is difficult to find the strain/stress sensitive area accurately, as well as the unique installation process, the calibration of resilient wheels is rather difficult. This paper takes the low floor resilient wheels as the research object, and studies how to make the calibration method of high precision and suitable for the independent rotating wheels of resilient wheels and the processing and analysis of calibration data. The main research contents are as follows: the development of force-measuring wheelset which is based on the finite element simulation of a resilient wheel, stress distribution analysis, and the fabrication scheme of force-measuring wheelset which meets the requirement of test accuracy is proposed by using virtual bridge formation.

Abstract:

The cutting ability of abrasive grains is considerably changed by wheel loading and leads to excessive rubbing at the wheel-work interface. Therefore, the wheel life, the overall performance of the grinding operation and the surface finish of the work piece are directly having an effect by the amount of loading over the wheel periphery. Wheel loading can, thus, be considered as an important factor for evaluating the grinding process. Though, few monitoring systems based on ultra sound and acoustic emissions are on the research anvil, they demand high investment. Monitoring of grinding wheel loading, using IR (Infra Red) which is affordable and cost effective for small scale industries is the scope of the present work. This work involves study on the temperature on cutting surface of grinding wheel during machining process. This information helps to understand the influence of temperature on wheel loading. In this respect, the experiments were carried out with Aluminium Oxide (Al2O3) and Silicon Carbide (SiC) grinding wheels over High carbon High chromium steel (HCHCr) and Mild steel specimens. The grinding wheels and specimens were chosen for pilot study, as they are widely used in Indian small scale Industries. The experiments were carried out with (WC) and without (WOC) general purpose soluble oil coolant. Temperature measurements were recorded at two locations on the grinding wheel to understand the distribution. The results show that the temperature rise during grinding was insignificant to cause any influence on the wheel loading.

Abstract:

Impact wheels and their effects on track have been studied extensively and used to justify the wide-scale deployment of wheel impact measurement systems to improve management and prevention of impact related damage to the infrastructure. Impact data has also been found to correlate with car failures including brake beams and bearings. While it is true that a disproportionately high percentage of catastrophic bearing failures have been associated with high impact wheels, it is also true that there are thousands of high impact wheels that do not result in catastrophic bearing failures. This paper examines both the effect of high impact wheels on roller bearing temperatures throughout their service life as measured using wayside bearing temperature detectors and the idea that a ‘braking event’ may start the long process of wheel deterioration.
