有轨电车客室空调机组降噪试验研究

Research on noise reduction of air conditioning unit for tram passenger room

在有轨电车车辆系统中车内噪声是评价乘客乘车舒适性的重要指标。车内噪声主要受空调系统的影响,在空调系统中通风量大小和空调噪声大小有着直接的关系。通过试验对比,优化通风机的匹配并做好良好的隔音降噪措施,对有轨电车客室内噪声有很好的抑制作用。可以大大提高乘客乘车的舒适度。

Abstract： In the tram system in the vehicle interior noise is an important indicator of evaluating passengers ride comfort. Noise inside the car is mainly affected by the air conditioning system. In the air conditioning system, the size of the ventilation and air con- ditioning noise has a direct relationship,Through experiment and eomparison, optimize the matching of ventilator and make good noise and noise reduction measures,On the tram passenger room noise has a good inhibitory effect. Can greatly improve passenger ride comfort.
