摘要
以二轮拖挂车的车身、车轮和路面障碍物为研究对象,通过动力学理论和车辆行驶试验对车辆侧翻现象进行分析。将路面固定障碍物简化为正弦半波形状,推导出车辆侧倾时的动力学方程,求解方程得到车辆侧翻的条件。由车辆侧翻试验观测系统实测得到侧翻速度和侧翻高度的关系,并将试验值和理论值进行了对比分析。
Taking the two-wheel vehicle＇ s tires and road obstacle as study object, the phenomenon of vehicle rollover was analyzed by dynamics theory and experiments. The road obstacle was regarded as the figure of trigonometric function. The dynamics equations were deduced by investigating the relationship between the obstacle and the whole vehicle. The critical condition of vehicle rollover was obtained by the solution of equation. The data of the velocities and height of rollover position were tested by experiment system. The theoretical result was compared with the experiments values, and the associated analysis was given in the paper.
