Abstract：Working conditions of piston ring-cylinder liner mate were simulated by SRV test rig. Friction coefficient and mass loss of mate under different static loads and vibration loads were tested. SEM-EDS were used to analyze wear marks and chemical composition. Wear mechanisms of piston rings-cylinder liners were researched. The results show that friction coefficient of mate decreases and mass loss increases with static load increasing. The main wear mechanism of mate is abrasive wear. The mechanism changes to abrasive wear and adhesion wear under 400N. Friction coefficient of mate appears cyclic change when loads alternate under low and moderate strength. The main wear mechanism of mate is abrasive wear. Friction coefficient of mate keeps stable under high strength. The wear mechanism of piston rings is comprehensive abrasive, adhesion and fatigue wear. The wear mechanism of cylinder liner is comprehensive abrasive, adhesion wear. Mass loss increases with strength of vibration load increasing.
