Mechatronic system of control position of wheel pairs by railway vehicles in the rail track

Abstract

The paper considers the possibility of guiding forces reducing and angle of attack minimizing during the movement of a rail vehicle in curved sections of the track with the help of modern control systems. The object is process of rail vehicles movement controlling. It is suggested to use mechatronic control systems for the position of wheel pairs in the horizontal plane for their radial installation in curved track sections for optimal interaction between the railway wheels and rails with achievement of minimum lateral forces and reducing wear. A particularity of such systems is the processing of signals from the global positioning satellite receiver, the inertial unit and the acoustic emission sensor in accordance with the levels at which the control action is generated for opening or closing the corresponding electromagnetic valves. Signal processing should be carried out in real time. It is noted that the probability of failure in the software of such systems should be very small. Only if these requirements are met it can be achieved the reliability of the mechatronic system built on these principles, as well as efficiency of the received information and the guaranteed execution of the command information. Proposed the wheel pairs position mechatronic active control system allows to optimally install them in the rail track under various driving conditions of the railway transport. The results of calculations made on the example of movement along the curve of a three-axle diesel locomotive 2TE116 bogie is showed the possibility of significantly reducing the guiding forces and minimizing the wheelpairs angle of attack.The paper considers the possibility of guiding forces reducing and angle of attack minimizing during the movement of a rail vehicle in curved sections of the track with the help of modern control systems.
