摘　　要：为了提高电动液压助力转向系统(EHPS)产品的设计质量,利用AMESim和ADAMS协同仿真虚拟实验的方法定量分析电动液压助力转向系统在不同转向工况下对汽车操纵稳定性的影响,检验和修正系统控制策略,提高车辆操纵稳定性能。在AMESim中建立电动液压助力转向系统仿真模型进行虚拟台架实验,获得系统的助力特性,在ADAMS中建立整车模型进行虚拟装车实验,包括蛇行实验、转向瞬态响应实验、转向回正性能实验、转向轻便性实验。分析高速转向时驾驶员手感和方向盘力大小、角阶跃输入时的反应时间、超调量和稳态横摆角速度、高速回正能力和低速回正能力以及低速转向的轻便性。In order to improve the quality of the design of EHPS,the influence of EHPS on handling and stability is researched by the co-simulation virtual test of AMESim and ADAMS,which is helpful to verify and correct the control strategy. The assistant characteristic is obtained by virtual bed test,which is finished by establishing the simulation model of EHPS in AMESim. The car model is established in ADAMS. The co-simulation virtual test that includes hunting test, transient response test, return-to-center test,portability test is finished,which is used to research handwheel torque ,steering feel of high speed,the time of response ,excess adjustment,yaw rate of steering wheel angle step input,the ability of return-tocenter and portability of low speed.
