摘要

利用考虑惯性力的Reynolds方程,对水润滑飞龙滑动轴承进行流体润滑数值分析。探讨不同载荷、转速以及表面粗糙度对压力和膜厚的影响,并与不考虑流体惯性力的热弹流解进行对比。结果表明,考虑流体惯性力的影响时,入口区压力增大,压力峰值有所减小,中心膜厚与最小膜厚均增大;随着载荷的增大,压力峰值增大,入口区的压力和膜厚减小;随着转速的增大,压力峰值减小,入口区压力及润滑膜膜厚增大;轴承表面粗糙度使得压力和膜厚均出现了连续波动,压力峰值增大,最小膜厚减小。

Abstract

Considering the inertial force in Reynolds equation,the thermal elastohydrodynamic lubrication analysis of the water- lubricated tenmat journal bearing is varied out. The effects of load,speed and surface roughness on the pressure and film thickness are discussed,and then compared with those without considering inertial force. The result show that as the fluid inertial force is considered,the pressure in inlet region,the central film thickness and the minimum film thickness are increased,but the pressure peak is decreased. The pressure peak is increased with the increase of load,but the film thickness is decreased. The pressure peak is decreased with the increase of speed,but the film thickness is increased. Considering the bearing surface roughness make pressure and film thickness oscillating,the pressure peak increased,the minimum film thickness decreased.
