气门-气门座的摩擦学设计研究

摘要

The working condition and the form of scuffing failure of valve-valve seat pair are introduced.The method of valve-valve seat tribology designing is provided.The dynamic condition of valve while the valve train working,the stress distribution and the axial deformation of valve head are calculated.The path to improve the durability of valve-valve seat pair is indicated.%介绍了气门-气门座摩擦副的工状况和失效形式，提出了气门-气门座摩擦学设计的方法；计算了配气机构工作时气门的动力学状态、气门头部的应力分布和气门头部的轴向变形，指出了提高气门-气门座摩擦副寿命的途径。
