| 摘 要： | 以某微型车为工程实例,在ADAMS环境下建立了车辆动力学模型,进行了变参数的直线制动仿真试验,以制动过程中的汽车动力学响应为依据,定量的分析了前悬架弹簧刚度变化对汽车制动效能和制动方向稳定性的影响,并解释了随着车速的增加汽车制动方向稳定性变差的原因.

| Abstract: | A multi-body dynamic model of a microbus according to SC and a road model ar established in ADAMS/View.Virtual tests of liner braking with varied parameters are carried out Influence of varied spring stiffness of front suspension on braking performance was analyzed quantitativel based on vehicle dynamics respond and tire-road state.The cause of poor braking directional stability with increase of velocity of vehicle was also analyzed. |
