摘　　要：文章采用一种流固耦合的计算方法,模拟某发动机排气歧管全速全负荷工作时的温度场以及冷却过程的变形与应力,由此确定该排气歧管在工作中变形过大、漏气问题的设计缺陷,并提出优化方案。A kind of CFD＆FEA coupling analysis method is adopted in this article to simulate an exhaust manifold＇s temperature, deformation and stress in its working cycle. The design defect which causes its excessive deformation and gas leakage is found by the analysis, and an optimization design plan is recommended.

关 键 词：排气歧管 流固耦合 温度场 变形 应力
