Innovative Multilevel Energy Processor in Machine Condition Monitoring
Working machine can be considered as an equivalent energy processor (EP) with internally limited energy dissipation. This means, we have limited machine lifetime and breakdown time, and the observed vibration symptoms of machine condition can be incorporated into EP model. Up to now one level of EP model have been in use, but using Singular Value Decomposition (SVD) we need two levels EP, and due to this it is possible to trace several independent faults of machine during its life. This possibility allow us to formulate concept of machine as a multilevel energy processor, and using SVD we determine the second sublevel of this multilevel EP. The present paper illustrates this way of thinking, and allows us to deepen our understanding of machine life and the wear on two levels; overall machine damage and particular functional faults as well.
