热边界条件对径向轴承的热流体动力润滑分析的影响
Effects of Thermal Boundary Conditions on Thermohydrodynamic Lubrication Analysis of Plain Journal Bearing
摘要
Abstract
A THD model of plain journal bearings was proposed herein.This model involved the synthetic solution of the generalized Reynolds equation,three-dimensional energy equation,and heat conduction equations of the solids.On the basis of that,series of results were provided to examine the effects of thermal boundary conditions.The results show the thermal boundary conditions have con-siderable effects on the THD analysis of plain journal bearings.Therefore,it is necessary to choose the thermal boundary conditions according to the actual operating conditions,so as to obtain reliable calculating results.关键词
