摘　　要：根据排气系统的走向布置,在轴承壳体外设计一个支架供排气三元催化支架固定,在耐久路试过程中,发现轴承外壳的这个支架开裂。文中通过观察实际安装状态,修正仿真连接模型进行问题查找分析,优化三元催化器支架及零件装配落差,以防止壳体再开裂。According to the exhaust system arrangement,to design a bracket on the bearing outer shell for exhaust ternary catalytic bracket,in the process of durable road test,found the bracket on the bearing outer shell cracking.In this paper,by observing the actual installation condition,to modify the simulation connection model for analysis and optimization of the ternary catalyst support and the assembly gap,to prevent the shell from cracking again.

关 键 词：壳体 三元催化器支架 装配落差
