高速铁道车辆噪声机理解析

The Resolution to the Noise Mechanism of High Speed Railway Car

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．

With the railway car speed increasing, noise also increases. The noise that passes to the inner of car can reduce passengers'riding comfort. And noise that passes to the outer of car can be harmful to wayside residents heavily. So the methods to reduce noise are very significant in realism. This paper resolves the noise mechanism of high speed railway car on the Japan Shinkansen and tests on existing car, at the. end puts forward the main methods to reduce noise.
