摘　　要：从理论上对多缸内燃机缸套 活塞系统摩擦学与动力学的耦合问题进行了研究。在纠正了到目前为止被广泛引用的活塞二阶运动方程中的错误的基础上, 给出了多缸内燃机缸套 活塞系统摩擦学与动力学耦合问题的数学模型。在该模型中, 首次在计算活塞二阶运动时考虑了连杆惯性力的影响。并对影响缸套 活塞系统摩擦学行为的主要动力学因素做了深入的论述。最后讨论了缸套 活塞系统摩擦学与动力学之间的耦合作用对活塞侧推力、作用在连杆和主轴承上的力的影响进行了讨论, 并据此对它们的传统计算模型作了修正。The coupling problem between the dynamic behaviors and the tribological behaviors of the piston-liner systems in multi-cylinder internal combustion engines was studied. Based on the correction of some errors in the equation of piston secondary motion, which have been employed by many authors for several years, a detailed mathematical model for the coupling problem between the dynamical and tribological behaviors in the piston-liner systems of multi-cylinder internal combustion engine was presented. In the model, the inertial force of the connecting-rod was involved in the calculation of the piston secondary motion for the first time, the primary dynamical factors that have impacts on the tribological behaviors in the piston-liner systems were discussed throughly, and the effects of the coupling process on the forces such as the piston thrust force, the connecting-rod force and the main bearing force were studied, and the traditional mathematical model of them were revised accordingly.
