摘　　要：有限元法(FEM)在结构分析中有着广泛的应用。通过对某车型前门建立有限元分析模型,分析其刚度,得出车门原有结构方案刚度值相比设计目标值有较大富余的结论,由此提出两种结构轻量化方案:改进车门加强板结构和采用激光拼焊板。两种方案都有效地减薄了车门料厚,达到了轻量化的目的。Finite Element Method（FEM） has wide application in structural analysis. By established FEM model and analyzed the stiffness of the front-door of one style automobile, come to a conclusion that value of stiffness of the original structure has a greater surplus compared to the target, then two lightweight schemes that improved the structure of stiffening plate on car door and using tailored blanks are put forward. The two schemes have both made the material thinner effectively, achieved the purpose of lightweight.
