Input Pressure Effects on the Static and Dynamic Characteristics of Hydrodynamic Lubrication Radial Sliding Bearing

研究了供油压力对液体动压径向滑动轴承动静特性的影响。运用有限差分法和适当的边界条件, 计算得出有无供油压力情况下, 轴承的动静特性参数, 并对计算结果进行分析比较。结果表明: 供油压力是分析液体动压径向滑动轴承动静特性的一个不可忽略的因素。

Input pressure effects on the static and dynamic characteristics of hydrodynamic lubrication radial sliding bearing were investigated theoretically. By means of finite differential methods and appropriate boundary conditions, static and dynamic characteristics of bearing under nonzero input pressure and zero input pressure were computed, and numerical results were analyzed and compared. The results show that input pressure is very important in the analysis of the static and dynamic characteristics of hydrodynamic lubrication radial sliding bearing.
