摘要
地铁车辆的车内噪声与轨道、车辆及隧道等诸多因素有关。通过对青岛地铁3号线车内噪声的测试与分析,探讨车辆运维及车辆设计制造方面的降噪措施。实测结果及其分析显示,车内噪声主要来源于轮轨噪声、车门型式和车体结构的隔声。因此,应从车辆设计、制造及运维角度研究车辆噪声产生原因,采取相应的措施降低车内噪声,提升乘客舒适度。
The interior noise of metro vehicle is related to many factors such as track,vehicle and tunnel.Based on the test and analysis of the interior noise in Qingdao Metro Line 3 vehicle,the noise reduction measures in the aspects of vehicle operation and maintenance and vehicle design and manufacturing are discussed.The measured results and analysis show that the interior noise mainly comes from wheelrail noise,door type and sound insulation of the body structure.Therefore,the causes of vehicle noise should be studied from the perspectives of vehicle design,manufacturing,operation and maintenance,taking corresponding measures to reduce the interior noise and improve passenger comfort.
