| 摘 要： | 本文以上具有不同弹性模量、泊松系数的两种轴承材料为例分析了弹性变形对有限长径向滑动轴承的弹流润滑性能的影响。流体动力润滑方程采用雷诺方程，应用力学问题的通用有限元软件ＭＡＲＣ产生柔度矩阵计算弹性变形。对比分析了二种轴承的油膜压力分布、油膜厚度分布、最小油膜厚度以及承载能力。

| Abstract: | Taking two bearing materials with different elastic modulus and different Poisson coefficient as examples,the effect of elastic deformation on the lubrication performance of finite journal bearing has been analysedThe Reynolds equation is utilized in the lubrication analysisThe influence function,calculated numerically using software MARC,is employed to compute the bearing deformationThe comparation results of the film thickness,the film pressure,minimum film thickness and load carrying capacity are pressented |
