车辆侧滑与侧翻的力学分析与避免方法

Mechanics analysis and avoidance method of vehicle sideslip and rollover

车辆侧滑与侧翻是道路交通的常见事故,侧滑从力学上分析主要是摩擦力不足以提供车辆做圆周运动所需的向心力,车辆只能以增大转弯半径的方式减小向心力,即发生侧滑;而影响侧翻的因素还决定于车辆的轴距和重心的高度。至于何种条件下发生侧滑或侧翻比较二者发生的临界速度可以得到,掌握侧滑和侧翻发生的条件就可以从主、客观两方面采取一定的措施加以避免。

The vehicle sideslip and rollover is the common accident of road traffic. Sideslip is caused mainly because the friction is not enough to provide the centripetal force needed for the circular motion of the vehicle. The vehicle can only reduce the centripetal force by increasing the turning radius,which causes the occurrence of sideslip. And the factors affecting the rollover are also determined by the wheelbase of the vehicle and the height of the gravity. Measures can be taken to avoid the accidents from aspects of subjectivity and objectivity by grasping the conditions of sideslip and rollover.
