摘要
利用拼焊板结构对已有车型的车门内板进行了改进研究,从而实现了减轻汽车重量的目的。推导了零件强度、抗凹性能和碰撞安全性能的轻量化控制方程,并以这些性能为设计约束,指导拼焊板结构的轻量化设计,使车门内板的减重效果达11.9%。整车侧面碰撞仿真分析表明,拼焊板改进设计后的车门内板相对于原始设计具有更高的耐撞安全性,验证了设计的可行性。
Aiming at reducing the weight of automobile, a study was performed to reaesign the inner door panel of an existing automobile using tailor-welded blank （TWB） structure. The lightweight governing equations of strength, dent resistance and crashworthiness were established to assist in the lightweight design as the constraints. The design reduced the weight of the automotive inner door panel by about 11.9%. Simulation results of side impact showed that the inner door panel with TWB structure performed better than that of the original design in crashworthiness, which confirmed the feasibility of this lightweight design.
