摘　　要：针对某车型在偏置碰撞试验中小腿得分较低的问题,对64 km/h偏置碰撞试验小腿失分过多进行原因分析,制定相应的结构优化方案,在CAE软件中建立有限元模型,通过试验验证了模型的准确性,利用该模型对改进方案和原方案进行分析对比,确定了可行方案,并将改进方案应用于实车试验中,结果表明,改进方案小腿得分大幅提升,所提出的优化方案可行。The author analyzes the causes of low calf score of offset collision test in 64 km/h for a vehicle model,makes corresponding structure optimization scheme,and sets up finite element model in CAE environment,and conducts test to verify accuracy of this model.The author also uses this model to compare the optimized scheme with the original scheme,to finalize a feasible scheme,then applies this optimized scheme to real vehicle test.The results show that the optimized scheme improves score of calf in offset crash test,indicating that the proposed optimization is feasible.
