Development of brake system test-bed for high-speed train

Abstract

As the speed of high-speed emu increases, the service conditions become more and more severe and complex. Brake system is an important guarantee of safety, so it is urgent to study the design concept and test method of brake system. There are relatively few researches on high-speed train brake test bench in China, and the existing test bench still has shortcomings in compatibility, real-time simulation and other aspects. Aiming at these problems, this work builds a brake test-bed for emu, which can complete the research test, performance test and reliability test of high-speed emu brake system and key components. At the same time, cooperate with Amesim, the braking process is simulated and predicted, and the braking process is analyzed by breakpoint, which provides a basis for the analysis, design and improvement of the braking system after experiment.
