摘要
结合对深圳某地铁车辆在静止状态、20 km/h、40 km/h、60 km/h和80 km/h运行速度下进行噪声试验,获得该车型车内噪声特性。试验结果表明,静止时车内噪声主要受到空调系统的影响;车辆运行时,轮轨噪声逐渐成为车内的主要噪声源,且随着速度的增加而增大。相关的分析结果可为地铁车辆噪声控制提供参考依据。
For a Shenzhen metro vehicle noise test in static,20 km/h,40 km/h,60 km/h and 80 km/h speed is carried out,get the interior noise characteristics of the vehicle. The test results show that the static interior noise is mainly affected by the air conditioning system,with the increase of running speed,the wheel and rail noise has gradually become the main source of vehicle.The results can provide a reference for the noise control of metro vehicles.
