随着人们生活水平的提高,乘客对地铁的舒适性提出了更高要求;因此保证乘客舒适乘车环境是一个值得思考的问题。减轻和降低车辆系统所产生的振动和噪声又是其中非常关键的环节。噪声是以空气为媒体传播,振动是通过固体传递的,减振降噪技术可以分为隔振、吸振、隔音、吸音四个方面。对于不同的噪声和振动,应该选择合适的减振降噪方法。
With the improvement of people’s living standards, passengers have put forward higher requirements on the comfort of the subway; therefore, it is a worthwhile consideration to ensure the comfortable riding environment of passengers. Reducing and reducing the vibration and noise generated by the vehicle system is another key link. Noise is the air as the media, vibration is transmitted through the solid, vibration and noise reduction technology can be divided into vibration isolation, vibration absorption, noise, sound-absorbing four areas. For different noise and vibration, you should choose the appropriate vibration and noise reduction methods.
