摘要
按照GB20071-2006法规对移动变形壁障性能的要求,建立了汽车侧碰移动变形壁障CAD模型,基于渐进式吸能块良好的变形特性,建立了相应的移动变形壁障有限元模型,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,分析表明模型满足法规的要求,为汽车侧面碰撞安全性仿真提供了必备的工具。
The CAD model of moving deformable barrier of vehicle side impact was established based on GB20071-2006 regulation.According to the excellent deformation characteristic of progressive barrier,the corresponding finite element model of moving deformable barrier was constructed.The simulation was carried out by the LS-dyna software.The results of simulation satisfy the regulation requirements.It provides the essential tool for the simulation of vehicle side impact.
