在该文中应用线性化的压粘方程对短径向轴承的润滑进行了计算,得到了油膜中压强的解析解,并以此解析解为基础,推导了承载量系数,摩擦力,功耗等公式.计算结果与一些文献中关于润滑现象的定性叙述是一致的,在该文中考虑压粘效应的公式化描述可为工程设计计算提供依据.“,”The linearized pressure-viscosity equation applied to the calculation of lubrication lor infinitely short joural bearing is studied in this paper. An analytical solution of pressure in oil films is obtained and the basis of this analytical solution, the formulae for coefficient of load-carrying capacity,friction and power losses are derived. The calculated results accord well with qualitive description on lubricant phenomenon in literatures. The difference between this paper and literatures which can be found at present time is that, in this pa-per the formulated description considering the pressure - viscosity effect provides the basis for engineering practice.
