Abstract

In this paper, the applicability of higher order wavelet transforms in detection of the local and transient phenomena hidden in vibration signals is investigated. Such phenomena may be, caused by a small defect in a mechanical system, such as a gearbox. It is shown that the spectrum analysis, based on an FFT algorithm, is unable to detect such events. Therefore, a method for, detection of inital and small defects gives certain advantages over other ethods.Although some researchers have investigated the FAULT DETECTION problem using the wavelet transforms, their works are mainly restricted to the lower order wavelet transforms like D2 to D8 Despite the complexity of obtaining the higher order basic wavelet functions such as D18, and D20 in this investigation it is shown that the higher order wavelet transfroms have more capabilities with respect to the lower ones. In fact, various signals have been analyzed using the different orders of wavelets, and the results have been compared. The results show the great ability of the higher order wavelets to detect the above mentioned local events. ,
