THE CONDITION MONITORING ABOUT ACAR ENGINE

초록

In previous work, the SWFOMS (Sliced Wigner Fourth Order Moment Spectra) for multiple signals had problems with its application, which were due to the existence of non-oscillating cross-terms not smoothed by conventional methods. In this paper, the g-method is developed to smooth non-oscillation cross-terms. The techniques developed are applied to the diagnosis of valve system faults in an engine.
