An Outputing Method of Kurtosis Value and Rotating Body Fault Diagnosis Method using the same

摘要

The present invention comprises the steps of sampling data through an acceleration sensor included in a certain area of the rotating body; Obtaining a standard deviation σ for all sections of the sampled data; Obtaining an average value μ for the entire section of the sampled data; Dividing the entire section of the sampled data into respective sections, and obtaining a standard deviation for each section to obtain a discrete deviation from signal x; And calculating the kurtosis value through the standard deviation σ, the mean value μ, and the discrete deviation from signal x. , A new method for calculating a kurtosis value for diagnosing an abnormality of a rotating body may be provided, and a rotational abnormality diagnostic method for diagnosing an abnormality of the rotating body may be provided using the method.
