摘　　要：为确定能够自动调平汽车的自激馈能式减振器设计方案的可行性,基于减振器内部结构及阀系特性,应用MSC.EASY5建立了自激馈能式减振器的仿真模型,应用ADAMS/CAR建立了某SUV的仿真模型,并通过ADAMS/CAR与MSC.EASY5之间协同仿真的形式实现了自激馈能式减振器与整车模型的集成;基于国标B级路面对所集成的整车模型进行了路试仿真试验。仿真试验结果表明,所设计的自激馈能式减振器能够回收车身振动能量,调节由于载荷变化引起的车身高度变化,对提高汽车性能具有积极意义。In order to confirm that automatic leveling system design of self-energizing shock absorber is viable, a mathematical model for self- energizing shock absorber was built using the software MSC. EASYS, the establishment of this model was based on the analysis of internal configuration and characteristics of valves. Debugging simulation of this model was also conducted. The vehicle simulation model was built u- sing ADAMS/CAR. The assembly between vehicle simulation model and self-energizing shock absorber was realized through co-simulation between ADAMS/CAR and MSC. EASYS. After the integration of the full vehicle model, the road test simulation based on random road sur- face was conducted. The simulation results show that, self-energizing shock absorber can partly recycle this energy and this recycled energy is used to adjust ride height because of load change of automobile. All these are meaningful for improving the performance of vehicle, so the research of self-energizing shock absorber is quite necessary.
