大学生方程式赛车（FSAE）差速器外壳结构优化的设计

摘要

This paper integrated the design for manufacture ( DFM ) and design for assembly ( DFA ) to optimize the structure of the differential shell . The primary consideration is high-efficient and high-qualified parts shape , to set up the concept of concurrent engineering or manufacturing engineers as members of the design team , and then according to the design principle for assembling to consider the extent to modify the design scheme , deal with the relationship between assembly costs and the entire product . Assembly design schedule is adopted to evaluate the original differential case and the new differential shell . The difference between valuation of the original differential housing scores and redesigned differential housing assessment score indicates the degree of improvement in assembly efficiency .%本文提出采用可制造性设计（DFM）和可装配性设计（DFA）集成的方法来优化差速器外壳的结构。首先考虑效率、高质量生产的零件形状的获得，建立并行工程的理念即制造工程师作为设计团队的成员，然后根据可装配性设计原则考虑在多大程度上修改设计方案，把握装配成本与整个产品的关系。采用可装配设计工作表对原差速器外壳和新差速器外壳进行评价，原差速器外壳的评价得分与重新设计的差速器外壳评估得分之差表示装配效率的改进程度。
