In this paper, 6th normalized moment of probability density function is introduced so as to intensify the sensitivity of diagnosis. Furthermore, simplified calculation method for this new parameter by impact vibration is introduced. Compared with the past papers' results, the proposed new method shows good result., Journal of economics, business and law. 2004, 6, p.45-58}, pages = {45--58}, title = {Simplified Machine Diagnosis Techniques by Impact Vibration using 6th Normalized Moment}, volume = {6}, year = {2004} }
