【摘要】 利用机械系统动力学仿真分析软件ADAMS,建立了一种新设计的四轮转向(4WS)汽车的整车虚拟样机模型。通过控制前、后轮转角的输入,实现了前轮转向与四轮转向,并在虚拟样机上分析比较了汽车四轮转向与前轮转向的主要瞬态动力学特性,结果表明:四轮转向汽车操纵稳定性优于前轮转向。更多还原

【Abstract】 A 4WS whole car virtual model is built with the mechanical multi-body dynamics software ADAMS.Forward-wheel Steering and Four-wheel Steering are carried out by controlling wheels′ rotating angle.After proceeding with virtual prototyping simulation,the transient dynamic characteristics of the car are analysed by using FWS and 4WS.The result of simulation declares that four-wheel steering car′ s manipulating stability is better than forward-wheel steering car′ s manipulating stability.更多还原
