Analysis demonstrates effective machine diagnosis using simplified models of kurtosis and normalized moments.
Among many dimensional and dimensionless amplitude parameters, kurtosis (4th normalized moment of probability density function) is recognized to be a sensitive good parameter for machine diagnosis. In this paper, simplified calculation method of kurtosis and 6^ normalized moment are introduced for the analysis of impact vibration including affiliated impact vibration. Various models are examined for these two models and it is shown that simplified calculation method of 6^ normalized moment is much more sensitive than those of kurtosis.
