Research on Rubbing Fault in a Dual-Disc Overhung Rotor-Bearing System

Abstract:

Mechanical model and rubbing force model of a dual-disc overhung rotor-bearing system are set up respectively. By using an experiment rig to simulate rubbing fault, the nonlinear dynamic characteristics of rubbing rotor system are investigated and the dynamic characteristics of mid-disc and overhung disc are analyzed respectively. The numerical simulation results coincide with the experiment results and the research in this paper has practical reference value to the safe and stable run of the practical rotating machinery.
