ESP液压执行单元柱塞泵动态特性仿真与试验
Dynamics Characteristic Simulation and Test of Pump of Hydraulic Control Unit of ESP
摘要
Abstract
Through the research of pump in hydraulic control unit ( HCU ) of electronic stability program (ESP) , a design method that actively build up brake pressure without pre-pressure was established. After that, a simulation model in AMESim to analyze the structure parameters of the HCU of ESP was proposed, especially the influence to increasing pressure rate with different pump flows and motor speed parameters. Based on the above, the pump flow and motor type can be defined when the hardware was matched by ESP. Finally, a bench test was carried out to prove the function of the pump that could build up pressure without a prepressing unit.关键词
