摘要

在缸套表面加工一定的纹理结构能有效提升缸套-活塞环的摩擦学性能,进而改善柴油机的工作性能和使用寿命。以环圆形凹槽结构为研究对象,在专用摩擦磨损实验机上对缸套-活塞环摩擦副进行模拟实验。研究了普通缸套和经表面处理的缸套在工况下的摩擦磨损性能。结果表明:环圆槽缸套的摩擦磨损性能优于原始缸套。该研究可为缸套-活塞环摩擦副的减磨耐磨设计提供实验依据。
        The tribological performances of cylinder liner-piston ring could be efficiently promoted by processing texture structures on the surface of the cylinder liner, and then the working performance and service life of diesel engine improve.Taking circular groove structure as research object, the simulaton experiment of a cylinder liner-piston ring friction pair was carried out by using special friction and wear tester. The friction and wear properties of common cylinder liner and cylinder liner after surface treatment under working conditions were studied. The results show that the friction and wear performances of the circular grooved cylinder are better than that of the initial cylinder liner. The study can provide experimental basis for the antifriction wear-resisting design of cylinder liner-piston ring friction pair.
