Abstract

Numerical simulation and analysis on the performance characteristics of the hydrostatically and hydrodynamically water-lubricated radial journal bearings are performed using the fluid analysis software FLUENT and MATLAB. Relationship between the bearing's primary parameters such as load carrying capacity, water film stiffness and the bearing's design parameters such as eccentricity ratio, supply water pressure is illustrated. It also demonstrates that water as a lubricant is not so efficient as mineral oil. Furthermore, experimental research is made on the hydrostatically water-lubricated journal bearing under different conditions. It is found that factors like radial bearing clearance, supply water pressure, running velocity all have influence on the performance characteristics of the bearing.
水润滑径向滑动轴承性能特性的数值模拟与实验研究
利用流体分析软件FLUENT和MATLAB对静、动水润滑径向滑动轴承的性能特性进行了数值模拟和分析。给出了承载能力、水膜刚度等轴承主要参数与偏心比、供水压力等轴承设计参数的关系。它还表明,水作为润滑剂的效率不如矿物油。并对不同工况下的静压水润滑滑动轴承进行了实验研究。研究发现,径向轴承游隙、供水压力、运行速度等因素对轴承的性能特性都有影响。
