Bearing Parameter Optimization of a Compressor Rotor System Based on Orthogonal Experimental Design

Abstract:

Article Preview

A Low-pressure cylinder rotor of certain large centrifugal compressor units was studied by combing orthogonal experiments and finite element method. The effect of bearing parameters (length-diameter ratio, clearance ratio, dynamic viscosity of lubricating oil and preload) to bearing-rotor system stability and journal vibration was evaluated and optimum bearing parameters were determined. The significant and non-significant factors influencing on system stability and journal vibration were determined by variance analysis and F test. These conclusions will provide guidance to compressor rotor system design.
