摘　　要：对径向滑动轴承进行了弹流润滑分析 ,利用了有限元软件MARC产生柔度矩阵 ,以近似计算轴承的弹性变形。对比分析了径向轴承的刚性流体润滑性能和弹性流体润滑性能。计算结果和已有文献资料良好吻合 ,表明在弹流润滑分析中用柔度矩阵法计算弹性变形具有良好的精度。A Study of the elastohydrodynamic lubrication of journal bearings has been given in this paper.The influence function,which is used to calculate elastic deformation,is obtained by the finite element software MARC.The hydrodynamic lubrication performance that doesnt take elastic deformation into consideration and the elastohydrodynamic lubrication performance of journal bearings have been compared.The results tally with the existing literature,which indicate that using influence function method in the elastohydrodynamic lubrication analysis of journal bearing can have favorable precision.
