摘　　要：文章采用MASTA软件的全有限元网格技术,在变速器模型中,对行星架进行有限元网格划分,并进行凝聚结点的自动计算,然后在整机约束条件下对行星架进行静力学仿真分析。新的计算方法实现了快速的零件受力分析,提高了工作效率,缩短了开发周期。Using the full finite element mesh technology of MASTA software, the finite element mesh of the planet carrier in the gearbox model is divided, and the automatic calculation of the condensed nodes is carried out. Then the static simulation of the planet carrier is carried out and analyzed under the constraints of the whole vehicle. The new calculation method enables rapid force analysis of parts, work efficiency is improved and development cycle is shortened.
