Experimental Study on Noise Suppression Effect of Wheel’s Tuned Mass Damper to Metro Vehicle
In order to study the noise reduction effect of wheel’s tuned mass damper, the train’s pass by and interior noise were measured with and without wheel’s tuned mass damper respectively according to the standard ISO3095-2005, ISO3381-2005, GB/T 5111-2011 and GB/T 3449-2011. The measurement results sho...

| description | In order to study the noise reduction effect of wheel’s tuned mass damper, the train’s pass by and interior noise were measured with and without wheel’s tuned mass damper respectively according to the standard ISO3095-2005, ISO3381-2005, GB/T 5111-2011 and GB/T 3449-2011. The measurement results showed that, the wheel’s tuned mass damper had no obvious noise reduction effect on the interior noise, and even slightly increased interior noise, the noise suppression effect of which was -0.7dB~1.5 dB; The existence of the wheel’s tuned mass damper had a better noise reduction on the pass by noise, the noise reduction level of which reached 1.2dB~3.1dB. For the frequency noise reduction property, the wheel’s tuned mass damper was effective for frequencies above 1000Hz. But for the frequency below 100Hz, the noise reduction effect appeared negative and increased the noise energy of corresponding frequency. At the same time, the noise reduction level and frequency property were similar for the near field sound radiation of the wheel and the pass by noise located at horizontal 7.5m and vertical 1.2m. This phenomenon indicated that, when the pass by noise was difficult to measure, the wheels’ near field sound radiation noise measurement could be used to evaluate the noise reduction effect of the low noise wheel on the pass by noise, which provided reference for low-noise wheel design and evaluating its noise reduction effect. |
