摘要/Abstract

摘要： 针对活塞环-缸套系统的摩擦行为建立了模型并进行数值求解，考虑了气穴现象和混合润滑的影响，研究了低黏度润滑油条件下织构对活塞环-缸套系统摩擦特性的影响，对比了在低黏度润滑油SAE0W20和SAE5W20的条件下活塞环表面含半径30μm、深度3μm的球形织构与不含织构的活塞环-缸套系统摩擦特性.结果表明：织构的作用与润滑油黏度密切相关；在润滑油SAE0W20的条件下，球形织构起到了一定的减摩作用；在润滑油SAE5W20的条件下，球形织构增大了系统的摩擦功率损失和摩擦平均有效压力.

Abstract: The paper built a numerical model for analyzing friction of piston ring-liner system, which considered the influence of cavitation and mixed lubrication. To investigate the synergistic effect of low viscosity and surface texture, two types of low viscosity oils, i.e. SAE0W20 and SAE5W20, were selected. Besides, the friction of piston ring with spherical texture, which was with a radius of 30μm and a depth of 3μm, was compared to the friction of piston ring without surface texture. The results show that the impact of surface texture is closely related to the viscosity of lubricating oil. Under condition of lubricating oil SAE0W20, the spherical texture helps to reduce friction, while under condition of lubricating oil SAE 5W20, the spherical texture increases friction power loss and friction mean effective pressure.

Key words: piston ring-liner system, low viscosity oil, surface texture, friction characteristic, mixed lubrication
