The clutch mechanism is the important part of printing machine. At present, cam connecting rod type mechanical clutch mechanism has been used by most of the domestic offset printing machine and its mechanical structure is very complex and its reliability is very poor. So a new type of pneumatic clutch mechanism is designed to meet its technological requirements. For the new mechanism, the motion law of the blanket cylinder can be calculated in the pressing process by complex number vector method and the finite element model has been established, natural frequency, maximum amplitude and mode of vibration of the cylinder can be calculated based on Block Lanczos method. The analysis results show that the relationship between the cylinders is flexible impact at the pressing instant, positioning is accurate, stable and reliable, which meets flexible design requirements. Thus it is important significance to improve design level and the product quality of the domestic printing machine and shorten the gap with foreign advanced printing machine.

The pneumatic control system for double-cylinder collaborative loading is extensively applied in the industry. However, compared to the hydraulic system, it is difficult for the pneumatic system for double-cylinder collaborative loading to get satisfactory effect due to strong non-linearity and low rigidity. To improve robustness of the double-cylinder collaborative loading system and increase its control precision, the double-looped PID hybrid controller and doublevariable neural network PDI controller are designed. The comparative test is performed for them in research. The research results indicate that the neutral network control is strongly adaptive to the unknown, uncertain and non-linear features of the controlled objects, can effectively overcome unfavorable influences of the non-linear factors on the system, and improve the control quality.

Control of a pneumatic actuator using pulse width modulation (control) represents a good alternative for control of pneumatic actuator that uses proportional valve. Important advantage of pulse width modulation control is fewer consumption of compressed air. In addition, air consumption can be further reduced by the use of inter-chamber cross flow (chamber by-passing). This article discusses joint application of pulse width modulation and by-pass chamber control on the example of pneumatic rodless cylinder which is controlled by programmable logic controller. Saving of compressed air was experimentally determined, as well as the influence of inter-chamber cross flow on the quality of the control. With this application of pulse width modulation and by-pass valve control, pneumatic actuator system shows that 30% of energy can be saved under the same working conditions in comparison to the traditional pulse width modulation control system.

The necessity to reduce the cost of timber haulage by logging road transport to increase the efficiency of logging in the Russian Federation has been substantiated. The drawbacks of the timber road transport equipped with traditional suspension systems, which are manifested when they transport timber along low quality logging roads, have been revealed. A promising direction for improving the operational properties of timber road transport used for hauling timber is described. It consists in the development of effective design schemes for suspensions for timber road transport with optimal suspension parameters. The scientific works of foreign scientists in this direction has been considered. Taking into account the identified shortcomings, a promising scheme of modular hydropneumatic suspension for timber road transport has been developed, which makes it possible to recuperate the energy of the working fluid when moving on the roads of low quality, compensate for leaks of working fluid, and also control the ground clearance from the driver's cab remotely. Two-factor optimization has been carried out, which allows identifying favorable combinations of the two factors under study. The graphs of the influence of the pneumatic cylinder diameter heat transfer coefficient on the maximum vertical acceleration of the sprung mass, as well as on the maximum gas pressure in the pneumatic cylinder and the amplitude of the temperature change have been obtained. The cartograms of optimization of the design parameters for perspective hydropneumatic suspension have been presented.

The manipulators arms are the most important components in automatic machinery and equipment. These arms must conform to product requirements and match important accessory devices such as clamping jaw so that the entire process operates properly. Therefore the most important issue is that the manipulator arm has only one clamping jaw, followed by other issues such as welding and related features. In this research the manipulator arm of automated machinery with attached equipment was optimized, and the design serves as an object of study for multifunctional applications. This research emphasizes on customized manipulator design to create products with distinguished styles and characteristics, and serve as a basis for an improvement on innovative design. Manipulator arms from different manufacturers with various head-disc size and screw-hole locations were investigated, and concept of human palm was incorporated in the design to create a mechanical fixture that can be fitted into the arm. Overall design including main body of the manipulator, pneumatic cylinder set, gear and connecting rod combination, planet gear set, and linkage rods and fixture. These components were combined to offer the functions of the manipulator. Commercial software package, SolidWorks, was used to construct the model for the manipulator arm, and CAE analysis was implemented to identify the stress on the structure and possible interferences of the mobile components. Stress analysis was also performed on the gear set under pneumatic loading to ensure that the gear mechanism has a sufficient strength. The results of this study showed that an arc shaped manipulator body is the most easily handled during installation and most effectively controlled during operation. The simple profiles of the manipulator also lower the space required for storage. The design of the gear set and integrated application of the shaft helps prevent loosening of gear and shaft during operation. In this study, a manipulator was designed with three different functions, each fixture is powered by an isolated pneumatic cylinder, and this mechanism can be manipulated to form o0to o180clamping action in accordance with requirements of the task. The methods and results of this study serve as a reference for machinery industry to achieve high quality product, and also as a basis for innovative design.

One of the limiting factors in increasing train speeds on railway transport is the quality of current collection. With increasing operation speeds, the dynamic loads on the current collector from the rolling stock increase and the aerodynamic impact increases as well, which leads to an increase in the variation of the contact pressure, tearing off the current collector from the contact wire, arcing in contact and increased wear of the contact elements. A promising direction in addressing this issue is the use of automatic control systems, allowing to stabilize the amount of contact pressure. The article discusses the features of modern automatic control systems for pressing current collectors, its main disadvantages are indicated. Authors proposed new automatic control circuit for pressing a current collector, characterized by increased speed. A mathematical model of a current collector equipped with a high-speed automatic pressure control system is described. The results of the calculation of the parameters of the high-speed control system are presented, showing the possibility of its use in order to reduce the spread of the contact pressure of the current collector and improve the quality of the current collection at high speeds. Analysis of the characteristics of the transfer functions of the regulator shows that the application of the PI controller algorithm is effective for stabilizing the contact pressure. Since the rod length of the pneumatic cylinder is limited, the regulator is able to maintain pressure for a limited time, after which the rod must be returned to its original position. The speed of the rod is limited by the characteristics of the actuator (electric motor). These features cause a significant variation in system parameters, such as the time constant and the duration of maintaining a stable depression, depending on the values of the controller coefficients kp and ki, which should be set taking into account the parameters of the current collector, operating conditions and type of contact suspension. For the considered current collector model, the optimal values of the controller coefficients are kp = 1.5 and ki= 1.0. Results of the calculations showed that the use of a rapid regulator based on a pneumatic cylinder in the carriage design reduces the standard deviation of the contact pressure to 37 % at speeds of up to 260 km/h.

Variable angle tow (VAT) laminates have shown enhanced stiffness/strength performance compared to conventional straight fiber laminates. Employment of VAT allows utilizing variable stiffness design of composite structure, thus it widens the design possibilities. As a result, composite structure with improved mechanical characteristics can be manufactured. The main aims of the current study are to give an overview on methods and algorithms used for analysis and design of VAT laminates, and to develop technology and equipment for manufacturing laminate with improved structural performance. In order to improve the accuracy of the compaction process, a set of experiments were carried out using a simple testing device. For measuring the compaction force, a pneumatic cylinder, pressure regulator and digital manometer were used. The temperature of the consolidation area and the heat distribution were screened with the thermal camera. Infrared heater was used as a heating source. Material used in the experiment was carbon fiber reinforced polyamide.Findings show that in addition to the main parameters – the compaction force and temperature, there are many minor factors, such as the compaction wheel diameter, material and surface roughness of the compaction roller, the material and surface roughness of the mold and the pretension in the laminating tape and also the laminating speed, all influence the quality of the final product.Key words: Advanced Fiber Placement Technology, Automated Fiber Placement, Automated Tape Laying, Fiber Reinforced Composites, Laminates

As a special kind of pneumatic cylinder, energizing pneumatic cylinder can increase the output force without changing diameter by a series of two or more piston on a piston rod. Since the friction characteristics of pneumatic cylinders is one of the most important factors affecting the nonlinearity, a new experimental apparatus is designed to have an in-depth study, base on exhaust throttle. The friction of energizing pneumatic cylinder was tested under different working pressure and velocity to ascertain the parameters of stribeck model. The results show that friction model of the energizing pneumatic cylinder can be the superposition of the models of each piston.

Friction always presents in pneumatic cylinders and causes difficulties in controlling position and velocity of pneumatic systems. In order to improve the control performance of the pneumatic systems, it is necessary to fully understand behavior of friction in the pneumatic cylinders. So far, dynamic friction behavior of pneumatic cylinders has been investigated but mainly focused on the friction behavior in sliding regime. In pre-sliding regime, friction behavior has not been investigated. In this paper, experimental investigations of friction behavior of a pneumatic cylinder in pre-sliding regime are made. The friction force is calculated from the equation of motion of the piston using the measured values of pressures in the two cylinder chambers and the piston displacement. The pressures are controlled by using two proportional pressure control valve. The friction force versus piston displacement characteristics are measured and analysed under various operating conditions of the applied force and the pressures. Experimental results show that: i) the piston motion in pre-sliding regime exhibits a nonlinear spring behavior; ii) hysteretic behavior with nonlocal memory is verified; iii) the pressures have influence only on the size of the hysteretic loop. These experimental results can be applied to develop a friction model for pneumatic cylinders.

This paper focuses on investigating friction behavior in pre-sliding regime and developing a new mathematical model of friction for fluid power actuators. Using pneumatic cylinders with different sizes, an experimental setup is built to measure friction force-displacement characteristics in presliding regime under various conditions of pressures in the cylinder chambers. A new mathematical model of friction for the pneumatic cylinders is proposed by incorporating a hysteresis function into the new modified LuGre model. The experimental results show that when the pressures are varied, friction of the pneumatic cylinders in pre-sliding regime is represented by behavior of a nonlinear spring. In addition, hysteresis behavior with nonlocal memory is obtained in the friction forcedisplacement characteristics and that the size of the hysteresis loop is increased with increasing pressures in the cylinder chambers. The simulation results show that the new friction model can accurately simulate the friction behavior of the pneumatic cylinders in pre-sliding regime as well as sliding regime.

In the situation of high-speed or heavy load, pneumatic cylinders usually generate cushion failure like collision or rebound, so that the key question to be solved for the cylinders is cushion. In order to obtain a better cushion method, the paper used the ideal cushion characteristic curve of hydraulic cylinders for reference; and throttling area equation, temperature equation, flow rate equation and motion equation were established. By building the simulation module in Matlab/Simulink, the rule of throttling area approaching to the ideal cushion curve was found, which provide theoretical basis for the design of cylinders cushion devices.

Pneumatic cylinders, as a long lifetime product, are used continuously under normal conditions. So Accelerated Life Testing is an important tool to get information quickly on lifetime which is achieved by subjecting the test cylinders to conditions that are more severe than the normal ones. This paper firstly analyze the failure mechanism of pneumatic cylinder, then based on the General Log-Linear relationship and Weibull distribution, describes a model for multiple stress-type accelerated life data analysis. The paper gives the parameter statistical method of the mode by using likelihood theory. Based on the test data from ALT of pneumatic cylinders which adopt four test stresses including air temperature, motion frequency, working pressure and operation velocity, the parameter of the model are fitted. According to the test data and the estimated model, the paper extrapolates the pneumatic cylinder’s lifetime information under the normal user level.

This paper focuses on the development of an efficient new diagnostic procedure for checking the function of pneumatic cylinders using acoustic emission. This diagnostic procedure is able to detect distinctive differences that determine whether the cylinder is damaged or undamaged. Moreover, the paper aims to find the diagnostic criteria that can be used to evaluate the pneumatic cylinder and detect defects. In this study, acoustic emission testing of several undamaged cylinders is carried out before artificial defects are created in each one. The signals from the progress and retreat strokes are recorded and analysed according to many parameters. The root mean square is normalised and the different responses of damaged and undamaged pneumatic cylinders are recognised by the time delay of the strokes. The differences are identified by comparing the maximum root mean square from sensor A and the maximum root mean square from sensor B for one cycle in the retreat stroke. The damaged and undamaged cylinders are distinguished using the difference in energy values present in the signals of the two sensors in the retreat stroke. The final evaluation of the cylinder is determined by calculating the total value of the root mean square. This paper is a continuation of a prior article and the extension of that work.

Nowadays, more and more industrial applications use pneumatic systems instead of hydraulic, electrical or mixed systems. This article presents the applicability of pneumatic engines for compressed air vehicles (CAV) from the perspective of their simulation on the Automation Studio software platform. It is desired to use the mechanical work produced by only pneumatic cylinders taken over by a mechanical system that transforms the linear motion into a rotational one, this helping to propel the CAV. A feature of this engine is the limited quantity of compressed air at disposal (a reservoir). Also, the most efficient operation of the pneumatic cylinders is studied to achieve the operation with low consumption of compressed air, thus leading to increased performances. The current simulation was run without the use of specific electric/electronic equipment (PLC /PACs). Therefore, the pneumatic devices had assured the command and control of the system.

The ball-and-plate system actuated by pneumatic direct cylinders is a typical nonlinear control system, which can be used to display the performance of pneumatic components and offer a test platform for the study of control theory. A control scheme of double-feedback-loop structure is utilized in this ball and plate system. A fuzzy-sliding mode controller is proposed according to the robust and fast response requirements of ball-and-plate pneumatic driven subsystem in the inner loop. A hardware-in-loop simulation system is established to test the trajectory tracking system. The experiment results show that the fuzzy-sliding model controller suits the robust and fast response requirements of pneumatic actuators. The trajectory tracking curves shows that the double-feedback-loop control scheme is suitable for the pneumatic ball-and-plate system.

A coordinated control method of manipulator driven by multiple pneumatic cylinders was proposed herein. Based on the characteristics of the strip-shaped products and processing requirements of the automatic packaging product line, a manipulator for clamping the products to performing the space position transformation and rotation was designed by using the software SolidWorks. The multi-cylinders sequential operational circuit composed of two rod-less pneumatic cylinders and three general pneumatic cylinders and the corresponding control valves was virtually debugged by using the software FluidSim. The control system was also constructed of PLC module with the touching screen, whose program was compiled and simulated in the software GX Developer and Simulator. And the monitor interface of the touching screen was developed in the configuration software GT-Designer, which is used to monitor the operation status of the PLC control system of the manipulator. Finally，experiments was performed on the proto device. Results of experiments demonstrated that the design method and constructing schedule of the manipulator could realize the grasping of multiple strip-shaped products and their space translation, rotation and packaging, and the manual packaging of the multiple strip-shaped products could be substituted with the manipulator.
