Ghost noise makes difficulty to find out which gear is the source in multi-stage gear-box. Against this problem, we had proposed discrimination method of ghost noise source gear pair due to amplitude fluctuation analysis. With the fundamental idea, it requires long continuous vibration measurement. In this study, we discuss vibration diagnosis of power transmission due to amplitude fluctuation analysis on virtual intermittent operation. The intermittent signals are converted from continuous vibration measurment results.
