内燃机活塞环——缸套三体磨粒磨损设计计算方法的研究

Research of the Wear Rate Calculation Method of Piston Ring—Cylinder Liner of Internal Combustion Engine

本文在考虑了油膜特性、形貌特性、磨粒特性、材料特性及工况条件等因素的基础上,导出了活塞环—缸套的三体磨粒磨损分析计算公式.经台架试验考核,该公式的计算与实验值有很好的一致性.

On the basis of the characteristics of the lubrication film, surface texture, abrasive particle material and work conditions, it sets up the wear rate analysis calculation formula of piston ring and cylinder liner. The calculated values are in good agreement with the experiment results.
