摘要
由于载货(客)的原因,汽车的重心会偏离原来的位置,进而影响汽车的行驶稳定性。以某微型车为工程实例,在ADAMS环境下建立了道路、车辆及车-路耦合模型,进行了虚拟试验仿真,以汽车的动力学响应为依据,定量地分析了重心位置的改变对汽车制动效能、制动方向稳定性的影响。
The gravity centre of vehicle often deviates from its primary position as a result of carrying cargo or passenger, In this paper, with the help of ADAMS/View,a multl-body dynamic model of a micro-vehicle,road and vehicle-road was established. Virtual test was carried out when the centre-of-gravity position of vehicle .was varied. The influence of centre-of-gravity position of vehicle on braking security was analyzed quantitatively based on vehicle dynamic respond and tyre-road state.
