Braking/Traction Control Systems of a Scaled Railway Vehicle for the Active Steering Testbed

초록

This paper describes the design of the braking/traction control systems as a part of a 1/5 scaled railway vehicle for active steering testbed which is to alleviate wheel/rail contact forces and to decrease wheel/rail wear. Active steering system of railway vehicles has proven its ability to bridge the gap between stability and curve friendliness. This system consists of two steering actuators, a steering controller, and various sensor systems to detect lateral displacement, vibration, track curvature, and so on. The control strategy of the braking/traction is founded on the velocity difference of two axle speed of the driving bogie. Running test results of 1/5 scaled active steering vehicle on the curved track show that the proposed braking/traction control systems has good performance.
