轿车EPS动力学联合仿真与分析

EPS Dynamics Combined Simulation and Analysis of a Sedan

汽车的安全性越来越受到重视,人们对汽车的操纵稳定性有了更高的要求。文章采用ADAMS软件,介绍了基于轿车EPS(电动助力转向系统)的机电一体化动力学仿真方法,并通过联合仿真试验研究了EPS对操纵稳定性的影响。从试验结果可以看出,装有EPS的汽车横摆角速度和车身侧倾角都得到了有效的控制,从而提高了汽车的操纵稳定性,满足了人们对汽车行驶安全性的要求。

Automotive safety has been paid more and more attention, high requirements of handling stability is needed. By using ADAMS software mechanical and electrical integration dynamics simulation method is introduced based on electric power assisted steering （EPS）. Through the combined simulation the effect of EPS on handling stability is studied. The experimental results show that the yaw angle rate and body roll angle of a car with EPS have been effectively controlled, handling stability is improved and the requirements of running safety is achieved.
