Using noise and vibration analysis system, the transmission system noise and vibration of a traction motor were tested, and the characteristics of the noise and vibration were analyzed. It is concluded that the noise level increases with the rotation speed increasing mainly in the frequency range near 800 Hz, and noise of MIC02 is higher than the noise of MIC01; gearbox vibration is bigger than motor vibration. This work provides a reference for noise and vibration reduction design of transmission systems of traction motors.

In vibration and noise reduction design of high speed train, sound quality has become an important indicator of comfort evaluation. In this paper, based on the theory by Zwicker who presented objective quantificational methods for subjective evaluation of the noise, the experimental data of internal noise of high speed railway trains is analyzed through the calculation of four objective evaluation parameters of noise: loudness, sharpness, roughness and fluctuation strength. Finally, the status and distribution regulations of various psychoacoustics parameters are obtained in the typical position of the train driven at several constant speeds. This work provides some reference basis for sound quality research of the high speed railway trains.
