摘要: 活塞环—缸套摩擦副的润滑状态直接影响着发动机的正常工作,缸套的磨损状况是决定发动机寿命的重要因素。对活塞环—缸套摩擦副进行了二维润滑分析,考虑了多种因素的影响,联解了二维雷诺方程、膜厚方程和载荷平衡方程。计算结果表明:活塞环—缸套摩擦副的润滑状态受多种因素的影响。同时计算结果也显示,通常采用的一维润滑分析有其局限性,对活塞环—缸套摩擦副进行二维润滑分析是十分必要的。

Abstract: Full numerical analysis of lubrication of piston ring-liner is developed and the Reynolds;equation, film thickness equation and force balance equation are solved by finite difference method. The detailed effects of many different factors are discussed. Calculatied results show that the lubrication performance of piston ring is significantly dependent on those factors. Some insights for the analysis of the performance of piston ring are provided.

Key words: Cylinder liner, Lubrication, Piston ring, Tribology
