摘　　要：通过有限元方法对齿毂和滑套进行强度分析,结合静扭试验结果对其进行改进,同时选择变速器总成静扭试验屈服扭矩最小的那组试验数据做试验仿真,得到同步器齿毂破坏的最大主应力做为判断依据,结果表明结构改进后的齿毂满足静扭试验强度要求。By means of finite element method,the strength analysis of the gear hub and slip sleeve is carried out,and the test data are improved by combining the results of static and torsional tests,and the maximum principal stress of the failure of the Synchronizer's hub is obtained by the test simulation,and then the maximal main stresses of the synchronizers are determined.The results show that the structural improvement of the gear hub satisfies the static and torsional test strength requirements.
