基于AMESim的离合器操纵系统建模及随动性能仿真分析

摘要

Servo performance of clutch operating system is one the important factors affecting vehicle performance and handling qualities.In this paper,according to the bond graph theory,a clutch operating system simulation model of heavy vehicle with hydraulic control and gas power-assistance is established in AMESim.Through testing,verify the correctness of this model.Using this modal,simulated servo performance of the clutch operating system,and analyzed quantitative the reason of the clutch pedal hard and abnormal wear under shifting of "continuous two clutch" conditions.%离合器操纵系统的随动性能是影响车辆性能和操纵品质的重要因素之一.该文利用键合图理论,基于AMESim软件建立了重型车离合器液压气助力操纵系统的仿真模型.通过相关试验,验证了仿真模型的正确性.利用该模型,对离合器操纵系统进行了随动性能仿真,并且定量地分析了导致“连续两脚离合器”换档工况下离合器踏板沉重以及离合器异常磨损的原因.
