Abstract

Abstract

The combined compressor rotor in not able to reach the maximum rating speed on test bench because its level of vibration is very high and exceeds vibration limits.This paper studies vibration of combined compressor by rotor dynamics analysis and experiments to discover the reason of fault.An advanced measure is taken and makes the combined compressor to operate normally.
