开关型动车组EP阀性能参数仿真分析

Simulation analysis of switch-type MU EP valve performance parameter

以动车组EP阀为研究对象,通过对EP阀工作原理的分析,利用多学科仿真平台AMESim软件建立EP阀的仿真模型,并针对不同工况对EP阀进行了仿真计算,重点研究了开关型EP阀PID控制死区参数K对EP阀性能的影响,为动车组制动系统的优化设计提供方法和理论参考。

Taking the MU EP valve as the research object, EP valve simulation model was made by multidisciplinary simulation platform AMESim software based on analyzing the working principles of EP valve,and simulation calculating of EP valve was performed according to different working conditions. The paper mainly studies the impact of PID controlling dead-zone parameter K on EP valve performance to provide methods and theory reference for MU braking system optimization design.
