| description | This paper outlines rotating machinery malfunction diagnostics using vibration data in correlation with operational process
data. The advantages of vibration monitoring systems as a part of preventive/predictive maintenance programs are
emphasized. After presenting basic principles of machinery diagnostics, several specific malfunction symptoms supported
by simple mathematical models are given. These malfunctions include unbalance, excessive radial load, rotor-to-stator
rubbing, fluid-induced vibrations, loose stationary and rotating parts, coupled torsional/lateral vibration excitation, and rotor
cracking. The experimental results and actual field data illustrate the rotor vibration responses for individual malfunctions.
Application of synchronous and nonsynchronous perturbation testing used for identification of basic dynamic characteristics
of rotors is presented. Future advancements in vibration monitoring and diagnostics of rotating machinery health are
discussed. In the Appendix, basic instrumentation for machine monitoring is outlined. |
