摘　　要：以歧管式净化器的工作特点及失效形式为切入点,通过稳态流场分析和瞬态流固耦合热应力分析两种方法找出了某型号产品在结构设计上存在的问题,并根据计算结果进行了结构优化。试验表明:优化后的产品符合国家标准要求,性能得到较大提升。采用CFD技术与试验相结合的方法为歧管式净化器的设计和优化提供了较为可靠的依据。As performance characteristics and failure mode of exhaust manifold catalytic converter be- ing breakthrough point, this paper determines main problems of a certain product through steady flow field analysis and transient fluid-solid coupling thermal stress analysis, and optimizes the structure ac- cording to calculation result. The tests indicate that, new model is accord with national standards and performance is improved greatly. It provides reliable basis for design and optimization of exhaust mani- fold catalytic converter Combining CFD and experiment.
