摘要
利用AMESim软件建立了汽车ESP回油泵模型。以上升时间tr、延迟时间td为阶跃响应动态评价指标,分析了回油泵主要设计参数对制动轮缸动态响应的影响,给出出油球阀直径、进油阀弹簧刚度是影响制动轮缸动态响应的关键尺寸参数,为国内设计制造ESP回油泵提供参考。
The AMESim software is used to establish the ESP pump model of automobile. And the influence of the main design parameters of the pump on the dynamic response of the brake cylinder is analyzed with the increase time tr and the delay time td. It is pointed out that the diameter of the outlet ball valve and the spring stiffness of the inlet valve are the key parameters that influence the dynamic response of brake wheel cylinder, providing theoretical basis for designing and manufacturing ESP pump in China.
