摘要
利用AMESim软件对汽车传统悬架和滚珠丝杠馈能式悬架系统进行建模。通过阶跃信号和随机不平路面两种激励振动仿真试验,得到车身垂直方向的位移和加速度响应特性曲线。并对两种悬架的仿真结果对比分析,证明馈能悬架的平顺性、阻尼特性和馈能能力的优势。仿真结果也为以后馈能式汽车悬架系统的研究及优化设计提供了新的理论依据。
Using AMESim to model the vehicle traditional suspension and energy regeneration suspension. The two simulation tests excited by the step function and the random rough road, the curves of vertical displacement and vertical acceleration of the vehicle body are obtained. Through the contrast and analysis of the two different suspensions, the advantage of energy regeneration suspension is testified on the ride performance, damping characteristic and energy regeneration ability. The simulation results provides a new theoretical for the optimization design of the vehicle energy regeneration suspension system.
