摘　　要：汽车侧面碰撞移动变形壁障是进行ECER95法规实验必需的工具,在侧碰仿真研究中必须建立准确的移动变形壁障模型。文中按照ECER95法规的要求,建立了汽车侧碰移动变形壁障的CAD模型,利用Hypermesh软件对所建立的移动变形壁障模型进行了前处理。最后利用LS-dyna软件对模型进行了求解,将仿真结果与法规要求进行了对比,并总结了调整模型材料参数的方法。分析表明模型满足了ECER95法规的要求,证明所开发的移动变形壁障模型可以用于汽车侧面碰撞的计算机仿真研究。Moving Deformable Barrier（MDB） of vehicle side impact is an essential tool for legislative verification of ECER95. The accurate model of MDB must be constructed in the computer simulation study of vehicle side impact. Based on ECER95 regulation , the CAD model of MDB is developed in the paper. Through the Hypermesh soft, the model is pre - processed. At last Ls - dyna soft is used to solve the model , the simulation result is contrasted to the regulation, and the method of adjusting the material parameters is summarized. The analysis indicates that the developed model satisfies the requirement of ECER95 regulation, It proves that the developed model can be used to computer stimulation study of vehicle side impact.
