| Outline of Final Research Achievements |
The purpose is to derive a method which can easily, quickly and accurately diagnosis machine faults. In this study, the method that can numerically determine faults situation of machine was developed by using correlation information of sound and vibration. More especially, a diagnosis method based on the estimation of the changing information of correlation between sound and vibration is considered by using prior information in only normal situation. Next, a diagnostic method which can detect the part of machine with fault for the specific multiple faults is proposed by measuring simultaneously the time series data on sound and vibration.
The effectiveness of the proposed theory is experimentally confirmed by applying it to the observed data emitted from a rotational machine driven by an electric motor.
