| Abstract: | Here, we use the technique of faultdiagnosis to determine the fault-cause for unqualified products and the main source of the noise, taking the rear axle assembly of automobiles as the object of study. So the orientation of scientific research could be clarified for improving the quality of products. We also briefly introduce a kind of noise silencer which we have developed recently, imitating the operating mode for the main source of the noise, and its vibration and noise reducing properties. |
