Simulation of Vehicle Handling and Stability Based on Hydraulic-Electrical Energy Regenerative Shock Absorber

Analyzing the influence of a proposed hydraulic-electrical energy regenerative shock ab-sorber (HESA)on vehicle handling and stability in different simulation conditions,it was proved that the HESA possessed a basic level with traditional hydraulic damper,and it was provided with a feasibility of real vehicle experiments.At first,the principle and damping characteristics of HESA were studied.Secondly,different simulation conditions were selected,such as double lane changing,steering wheel angle step and fishhook test.And the yaw velocity,roll angle and lateral acceleration were selected as the evaluation indices to evaluate the HESA's influences on vehicle handling and stability.At last,the motor displacement,check valve cracking pressure and pipe diameter were taken as the main influential parameters to analysis the effect on vehicle handling and stability.The results can provide a theoretic foundation for suspension matching.
