摘　　要：利用ADAMS建立了新型四轮转向汽车整车虚拟样机模型,在ADAMS/CAR中建立了四轮转向汽车(4WS)前后轮转角比例控制与横摆角速度反馈控制的关系,在此基础上对四轮转向汽车与二轮转向汽车的整车瞬态特性、稳态特性进行了对比仿真分析,对轮胎侧偏刚度对转向性能的影响进行了研究,仿真结果表明,四轮转向汽车具有低速机动灵活和高速稳定的优点。A new style 4WS vehicle virtual prototype was estab- hshed based on ADAMS.The proportional control relationship of the front and back wheels＇ angles and the feedback control relationship of yaw rate were presented. The transient response and the steady-state performances of 4WS and 2WS vehicles were analyzed,and the influence of tire lateral stiffness on steering performance was studied.The simulation results indicate that the 4WS vehicle takes on rather agility at the low speed and excellent stability in at the high speed.The future developing trends with 4WS system control technology was prospected in the end.
