Software ANSYS and FORTRAN program were combined to carry out the numerical simulation of the model.

A model was established to analyze the coupling effect between the dynamic behavior and lubricating behavior of a cylinderpiston system in an internalcombustion engine. Software ANSYS and FORTRAN program were combined to carry out the numerical simulation of the model. Thus the finite element method model of the cylinder was established and its transient dynamic response computed with the ANSYS software. The lubrication of the cylinderpiston pair was simulated with an average Reynolds equation considering the secondvibration of the piston. The timedependent minimum film thickness, friction force, and friction power loss were calculated making use of sequential fieldcoupling analysis. It was found that the coupling action between the lubricating behavior and dynamic behavior of the cylinderpiston system had significant effects on the lubricating characteristics as compared with the analytical results excluding the vibration of the cylinder. Namely, in consideration of the cylinder vibration, the cylinderpiston system registered larger friction force, friction power loss, and oil film thickness variation.

建立了缸套-活塞系统油膜润滑与动力学行为耦合分析模型,并用数值方法进行了仿真计算,用有限元法计算了缸体的结构动力响应;通过采用有限差分法求解平均雷诺方程计算了缸套和活塞间的流体润滑特性,并探讨了活塞二阶振动的影响;采用顺序耦合的方法计算了考虑缸套-活塞摩擦、润滑与缸体结构振动、活塞二阶振动耦合作用的缸套-活塞间最小油膜厚度变化、摩擦力及摩擦功耗等.同不考虑缸体振动时的相应分析和计算结果对比发现,缸体结构振动对油膜润滑特性具有重要影响.

An analysis model of coupling engine block dynamics behavior to lubrication in cylinder piston system in internal combustion engine was established, and the numerical simulation of the model was processed through linking ANSYS software to FORTRAN code for lubrication. The finite element model of an engine block was built, and its transient dynamics response was computed with ANSYS. The lubrication of cylinder piston pair was simulated with an average Reynolds equation considering the second vibration of the piston and the asperity contact of rough surface. The trajectory of piston secondary motion,the minimum oil film thickness, the friction force and the friction power loss etc. vs. time were presented. Comparing with the results of the analysis without considering vibration of cylinder, it is evident that the coupling of tribological behavior and dynamics behavior in cylinder piston system is very strong. For the vibration of the cylinder, friction force and the friction power loss of the cylinder piston system become less, the minimum oil film thickness, the displacement and the velocity of piston secondary motion become larger.

建立了内燃机缸套 活塞系统油膜润滑与动力学行为的耦合分析模型,并用数值方法对单缸四冲程内燃机进行了仿真分析.在分析中同时考虑了活塞二阶运动和缸体振动对缸套 活塞间油膜润滑的影响.缸体结构振动响应用有限元法来计算,缸套和活塞间的流体润滑计算通过有限差分法求解平均雷诺方程进行,其中考虑了微凸体接触的作用.在考虑缸套 活塞油膜润滑与缸体结构振动、活塞二阶运动耦合作用的情况下,计算出了缸套 活塞间润滑油膜的最小油膜厚度、摩擦力、摩擦功耗等,同时也分析了活塞二阶运动的变化.通过与不考虑缸体振动时的相应结果对比表明:考虑缸体的结构振动后,缸套 活塞间的摩擦力和摩擦功耗减小,油膜厚度、活塞的二阶运动位移及速度增大.
