针对客车结构在侧翻碰撞变形部位无法增加有效的吸能元件的特点，提出一种弹出机构侧翻保护方案，在尽可能不增加成本的前提下改善客车侧翻安全性能。该弹出式机构，在车体即将接触地面的时刻使某一行李舱门迅速弹开，先于车身本体结构与地面接触，产生均匀变形并吸收能量。车身段侧翻仿真与试验验证了该方案的侧翻保护效果，最后，对该结构进行轻量化改进设计。

In view of the feature of bus structure that it is hard to add effective energy absorbing elements in deformation region during rollover, a rollover protection scheme with pop-up mechanism is proposed without too-much cost rise. When the body is about to touch road surface, a luggage compartment door with pop-up mechanism quickly opens,hits the ground, deforms evenly and absorbs impact energy before vehicle body does. The body sec-tion rollover simulation and test verify the rollover protection effects of the proposed scheme. Finally a lightweighting modification design is conducted on the structure of body section with pop-up compartment door.
