摘　　要：摘要本文采用H. Christensen提出的随机粗糙模型,推导了径向轴承的纵向粗糙和横向粗糙型的雷诺方程和相应的承载力、流量系数、摩擦系数公式.对有限长径向轴承的两种粗糙型雷诺方程用差分方法进行数值求解,得到了粗糙度对轴承的承栽力、流量系数和摩擦系数影响的图表,并对实例进行了粗糙轴承的轴心轨迹的计算和分析.Reynolds equations for longitudinal and transverse rough journal bearing and their corresponding formulas for load capacity, oil flow, and coefficient of friction were derived using the stochastic theory of roughness developed by H.Christensen. Numerical solutions of the two rough type Reynolds equations and effects of bearing roughness on load capacity, oil flow, and coefficient of friction shown in curves and tables were presented. As an example, the journal center orbit of a practical rough journal bearing was calculated and analyzed.
