Research of complex rotary systems vibrocondition based on analysis of dynamical processes and spectrum of vibrations

Abstract

Mechatronic systems designed for monitoring and control of complex rotary machines can be implemented effectively only when alarm or critical levels of monitored parameters are well known and the sources of their devia-tions can be determined. Vibrodiagnostics is a powerful tool which can be used for the determination of machine defects. However, in case of complex rotary machines, it is very complicated to trace all sources of vibrations (e.g. internal defects). Therefore attempts of vibrations model-ling are made aiming to evaluate the influence of various parameters on the vibroactivity of certain machine.
