随着铁道车辆速度的增加,噪声也随之而加大,噪声传递到车内,会使乘客的乘车舒适度降低;传递到车外,会使铁路沿线两侧的居民深受其害.因此,如何降低车辆噪声具有较高的现实意义.通过对日本新干线高速铁道车辆进行噪声机理解析和现车试验,提出了降低噪声的主要方法.
As the speed of railway vehicles increases, the noise also increases. The noise is transmitted to the vehicle, which will reduce the ride comfort of the passengers. Passing to the outside of the vehicle will make residents on both sides of the railway deeply injured. Therefore, how to reduce vehicle noise has a high practical significance. Through the analysis of the noise mechanism and the current car test on the high-speed railway vehicles of Shinkansen in Japan, the main methods of noise reduction are put forward.
