摘　　要：建立了汽车发动机气缸盖、气缸垫与冷却水组合结构有限元分析的三维CAD/CAE应用软件集成系统,采用固流耦合分析方法确定了固流独立个体的耦合热传递边界面,通过单元转换,在单一模型中完成了流场、温度场和应力场的计算,与试验结果对比,计算误差满足工程设计要求,可为气缸盖与气缸垫组合设计提供一定的理论依据。The 3D CAD/CAE integrated system is built up which developed for engine cylinder head, head gasket and coolant system by means of finite dement analysis software. Determining coupling thermal transmission border trades of fluid-solid independent individual adopting of fluid-solid coupling. By units converting, the calculation of flow field, temperature field and stress field was carried out in single model. Compared with experiment results, counting error is satisfied with request of engineering design ,which can supply theoretical foundation for unitized design of engine cylinder head and head gasket.
