推导客车侧翻的临界碰撞时刻的角速度，从能量转化的角度分析客车的侧翻过程，阐述不同摩擦副上客车侧翻性能的差异。最后通过仿真分析不同摩擦副上客车的侧翻情况，得出摩擦副摩擦系数与客车骨架变形程度的关系。
推導客車側翻的臨界踫撞時刻的角速度，從能量轉化的角度分析客車的側翻過程，闡述不同摩抆副上客車側翻性能的差異。最後通過倣真分析不同摩抆副上客車的側翻情況，得齣摩抆副摩抆繫數與客車骨架變形程度的關繫。

The coach angular velocity of critical collision moment is deduced while a coach is rolling over. The rollover process is analyzed from the point of view of energy transformation. And the difference of coach rollover per-formance under different friction pairs is presented. At last, by simulating the coach rollover situation under different friction pairs, the authors get the relationship between friction coefficient of friction pairs and the deformation extent of the coach framework.
