摘　　要：利用滑动轴承的静、动特性列表数据，考虑到滑动轴承的几何参数和载荷的离散性，用Ｍｏｎｔｅ—Ｃａｒｌｏ方法对滑动轴承的最小油膜厚度、油膜刚度系数、阻尼系数进行统计分析。根据设计准则计算滑动轴承可靠度，由统计结果选择轴承的粗糙度或其他参数。In this paper, the statistical nature of the minimum thickness of the oil film, stiffness and damping coefficients of the sleeve bearings have been investigated by the Monte-carlo method, according to the listed data of static and dynamic performances and taking inevitable manufacturing errors into account as well as discreteness of load. Depending upon the design criteria, the reliability of the bearings can be calculated,or the roughness of bearing surface chosen by the statistical results.
