摘要

摘要: 在基于有限体积法的流体仿真软件FLEUNT中,对层流状态下的液体动静压油膜-轴承这一流固耦合模型进行了数值仿真,得出了动静压轴承的温度分布情况;并进一步在有限元软件ANSYS中对轴承的热变形情况进行了分析计算。结果表明:轴承的最高温升及径向最大热变形随主轴转速和偏心率的增大而迅速增大,随环境温度的升高而减小;而供油压力对轴承热变形的影响不大。且轴承径向最大热变形值和轴承间隙在同一数量级,因此热变形在动静压轴承性能分析中不可忽略。

Abstract: In its laminar flow state,the liquid and solid coupling model of oil film and liquid dynamic and static pressure bearing was solved with the FLEUNT software. The thermal deformation of the bearing was calculated with the ANSYS software based on the finite element method. The analysis results show that,the values of maximum temperature rise and maximum radial thermal deformation of the bearing increase rapidly with the increase of rota-tional speed and eccentricity of the bearing and decrease with the increasing ambient temperature,while the inlet oil pressure of the bearing has little effect on the values. The values of maximal radial thermal deformation of the bearing and the values of its clearance have the same order of magnitude,so the heat distortion is not ignorable in analyzing the bearing.
