【摘要】 为实现车辆的动力学特性在虚拟环境下的仿真和预估,基于ADAMS/Car环境建立整车动力学虚拟参数化模型。按照ISO规定的汽车操纵稳定性试验条件,研究模型的瞬态和稳态响应特性,包括横摆角速度和侧向加速度的响应特性,在角阶跃输入下高速转弯时,对4WS汽车和FWS汽车分别做了操纵动力学仿真和试验研究。仿真结果表明,四轮转向车辆控制系统具有良好的动态性能、鲁棒稳定性和鲁棒性能。更多还原

【Abstract】 To achieve vehicle dynamic characteristics simulation and estimation at virtual environmental conditions for growth and development,One virtual dynamic parameterized model of 4WS vehicle is made in this paper based on software-ADAMS/Car.According to road vehicle test ISO standard,This paper analyzes the characteristics of transient and steady dynamic responses of 4WS vehicle,yaw velocity and lateral acceleration responses between 4WS and FWS vehicle are compared and analyzed when it is turning at high speed under the condition of step input.Characteristics.The results of simulation show that the control system has fine dynamic characteristic,robust stability and robust performance.更多还原
