For the case that the stainless steel manifold catalytic converter of a certain car breaks in the experimental process , cold and hot modal analysis were conducted to determine the fracture causes .Several programs based on the results of the analysis were put forward to improve the structure .The reasonableness of the program was verified by finite element analysis .The final solu-tion was obtained by comparison and analysis .And finally the feasibility of the final program was proved by experiment .
