Abstract

To identify the noise sources of truck crane drive axle, noise signal was analysed by improved continuous wavelet transform (ICWT).The results indicate that the noise of the drive axle is directly caused by its surface radiation, which is due to the various dynamic stresses produced by gear meshing. Drive axle's noise energy mainly distributes in the gear meshing frequency or its octave, and the main resources of excitation and noise is the gear meshing. The results of the non-stationary noise signal transformed by ICWT can properly show not only their frequency characteristics, but also their time characteristics. ICWT is more appropriated for time-frequency analysis.
