摘要

摘要: 为探究活塞环表面织构密度对船舶柴油机缸套-活塞环这一主要摩擦副的摩擦性能的影响，利用具有不同织构密度圆形凹坑的活塞环在MWF-10往复式摩擦磨损试验机上进行试验。通过调整试验载荷、转速获取了不同模拟工况下的测试数据，结合对应参数分析了活塞环织构密度对缸套-活塞环摩擦副的摩擦作用影响。结果表明：带有不同表面织构密度圆形凹坑的活塞环可以在不同程度上降低摩擦副的摩擦系数，提高其摩擦学性能。综合摩擦系数、表面形貌的相关分析可知：在载荷一定时，存在合适的织构密度（${S\!_p}$= 20.9%）能够显著降低缸套-活塞环摩擦副的摩擦系数，同时可以减少摩擦副的磨损量，提高摩擦副的综合摩擦性能。

Abstract: The cylinder liner-piston ring (CLPR) is one of the main friction pair in marine diesel engine. To investigate the influence of the texture density in the surface of piston ring on the tribological performance of CLPR, piston rings with circular dimples of different texture densities were tested on the MWF-10 reciprocating friction and wear tester. The test data under different simulation conditions were obtained by adjusting the tested applied loads and rotational speeds. The influence of the texture density in the surface of piston ring on the friction pair of the CLPR was analyzed with the tested parameters. The results indicate that the piston rings with circular pits at the different surface texture densities can reduce the friction coefficient of the friction pair to different degrees. The results indicated that circular textured piston rings with different texture densities could reduce the friction coefficient and improve their tribological properties to different degrees. According to the comprehensive analysis of friction coefficients and surface morphologies, it can be known that when the load is constant under the tested conditions, an appropriate texture density (${S\!_p}$= 20.9%) significantly reduced the friction coefficient and wear loss of the CLPR friction pair. And then the comprehensive tribological performance of the CLPR friction pair was improved.
