基于有限元的轴承参数变化对离心式压缩机转子固有特性的影响研究

Research on the Effect of Bearing Parameter Change on the Natural Characteristic of Large Centrifugal Compressor based on Finite Element

基于有限元软件,建立了一种压缩机转子动力学有限元模型;通过轴承参数的变化,分别研究了轴承润滑油温度、轴承间隙比、长径比对系统固有振动特性的影响。

A rotor dynanfics finite element model of large centrifugal compressor is established by the finite ele- ment software. Based on this model, the different effects on the compressor rotor system natural vibration characteristic of bearing parameters are studied including lubricant oil temperature, clearance ratio and lengthdiameter ratio.
