| Abstract: | this paper introduces the importance of the bracket on engine three-way catalyst, whose fatigue life must be guranteed. Aimed at the problem of fracture occurred in The engine bench test, fatigue analysis is carried out on the bracket by using the Pro/mechanica finite element analysis, than optimization of the recommendations is put forward, and the optimized structure finite element analysis is carried out again to verify. |
