Abstract:

The vibration and noise of driving motor is one of the prime reasons of the vibration and noise of electric driving mining truck, which seriously affects the comfort of the vehicle. A test platform for the driving motor of mining truck was set up, and the noise and vibration testing for the driving motor was carried out. The main characteristic frequency and the main sound vibration source of the electric drive motor were obtained by combining the spectrum analysis and the coherent analysis. Therefrom, the measures for reducing the vibration and noise were put forward. The results of the study provide an experimental support for the optimization of acoustic and vibration characteristics of mining motor.

Key words: mining motor, characteristics of vibration and noise, spectrum analysis, vibration and noise reduction
