要約(日本語): Among many dimensional and dimensionless amplitude parameters, Kurtosis(4-th normalized moment of probability density function) is recognized to be the sensitive good parameter for machine diagnosis. Kurtosis has a value of 3.0 under normal condition and the value generally goes up as the deterioration proceeds. In this paper, simplified calculation method of kurtosis is introduced for the analysis of impact vibration including affiliated impact vibration. Affiliated impact vibration is approximated by triangle and simplified calculation method is introduced. Furthermore absolute deterioration factor is introduced. Varying the shape of triangle, various models are examined.
Newly proposed method proved to be a sensitive good index for machine diagnosis.
