IDENTIFICATION OF HIGH-ORDER CRITICAL SPEED TO ROTOR BEARING SYSTEM

Abstract

Abstract: Critical speed is one of the important dyrmrnic pararaeters of the rotor system in centrifugal compressor. With the rotational speed increasing, the problem of passing the two or more higher order critical speed is appeared, so it is very important to identify the high-order critical speed of one rotor system during its trial run. The vibration signals of rotor system are analyzedby harmonic wavelet I then the high-order critical speed is identified. The fmal result is satisfying.

Key words: Critical speed, Rotor system, Harmonic vvavelet
