摘　　要：为研究国内某型拖挂式房车的抗撞性是否符合国家安全标准,对其进行了侧面碰撞仿真分析。首先创建了该房车和移动壁障的有限元模型,定义了材料、属性、接触等参数,然后导入LS-DYNA进行求解,得到输出节点的结果参数,最后参照汽车侧面碰撞相关安全法规进行评价,得出该拖挂式房车符合汽车侧面碰撞的安全标准。In order to study whether the crashworthiness of a tractor-trailer car in China meets the national safety standards,side crash simulation analysis was carried out.Firstly,the finite element model of the car and the moving barrier is established,and the parameters of material,property and contact are defined.Then LS-DYNA is imported to solve the problem,and the result parameters of the output node are obtained.Finally,the safety standard of the car side crash is obtained by referring to the relevant safety regulations of car side crash.

关 键 词：拖挂式房车 侧面碰撞 LS-DYNA 移动壁障
