Abstract: 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.EASY5, 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 using ADAMS/CAR. The assembly between vehicle simulation model and selfenergizing shock absorber was realized through cosimulation between ADAMS/CAR and MSC.EASY5. After the integration of the full vehicle model, the road test simulation based on random road surface 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.
