Experimental Study on the Noise Identification of the Rear Driving Axle
Firstly, based on the theories and methods of acoustic array measurement, the surface radiation noise of the rear driving axle of minibus was tested in the bench experiment. With the analysis of the experiment data, sound holography contour map was used to plot the noise distribution of the rear driving axle. It is found that the major noise source closes to the case of main reducer of the driving axle. The major noise frequencies are related to the gear meshing vibration. These results basically coincide with the sound intensity experimental results.
