摘　　要：以某微型车为工程实例,在ADAMS环境下建立了多自由度的整车动力学模型,给出了稳态圆周试验的虚拟实现方法,在后悬架中加入横向稳定杆模型,调整稳定杆的角刚度,有效地控制了该微型车因为发动机前置造成的过多的不足转向特性,还分析了汽车的质量分布对转向特性的影响。A multi-body dynamics model of a microcar was built in this paper with the help of ADAMS/View. Virtual test method of steer stability was obtained. Dynamics model of anti-roll bar was added to the rear suspension model. By rectifying the stiffness of the rod,over-steer characteristics resulting from placing engine forward was improved. Moreover,distributing effect of automobile mass on steer characteristics was also analyzed.
