摘　　要：汽车侧翻是一种致命的交通事故,大多是由于驾驶员操作不当引起的。为精确分析汽车侧翻动力学性能,基于ADAMS软件建立了汽车侧翻的多体动力学模型;采用横向载荷转移率作为汽车侧翻的评价指标,对驾驶员能够控制侧翻因素(如方向盘转角、方向盘转速,以及特殊情况的转向频率)进行了定性分析,获得了驾驶员因素对汽车侧翻的影响规律。结果表明:随着驾驶员的方向盘转角和转速的增大,汽车侧翻的危险性也随之增大。Vehicle rollover is a serious fatal traffic accident. Most of rollover accidents are caused by driver＇s improper operation. To study the influence of driver＇s action on vehicle rollover stability,a multi-body model of vehicle was established using ADAMS software. And also the lateral load transfer ratio was used to evaluate the vehicle rollover risk. Then,some influence rules of driver＇s factors（ such as the steering wheel angle,steering wheel rotation speed,and special circumstances to frequency） on vehicle rollover were obtained by analyzing multi-body dynamics of vehicle. The results show that large steering angle and steering rate will increase vehicle rollover risk.
