摘　　要：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 section 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.
