| 中文摘要: |
| 为确定某型车用发动机飞轮壳与齿轮室的密封方式，对其接触面进行面压力有限元模拟计算。建立并简化气缸体、齿轮室、飞轮壳的三维模型，通过前处理软件划分3D网格，将网格模型导入到ABAQUS软件，运用ABAQUS下属Standard3D模块进行面面接触分析。分析所得结果为组件装配后齿轮室与飞轮壳的接触状态；再将此状态与两种待选密封胶的使用条件进行比对发现：待密封面上存在多处面压过小的区域，不能满足厌氧胶的使用条件。最终确定有机硅胶为可行的密封方式，为发动机的设计工作提供必要的支撑。 |

| In order to determine seal mode between the engine flywheel and gear chamber of a car, the surface pressure on their contact surfaces was analyzed by finite element simulation. The 3D model including cylinder block, gear chamber and flywheel was built and simplified. By pre processing software, 3D mesh was generated. The model was imported into ABAQUS. Then, according to the principle of surface to surface contact, the contact state between the flywheel and gear chamber was analyzed by standard3D module. After this, comparing the working conditions of two selected sealant, it is found that there were many areas on the surface to be sealed, whose surface pressure is too small, cannot meet the anaerobic use conditions. Therefore ultimately a viable silicone seal is selected. The research provides theoretical basis for the engine designing.
