摘要

为提高高速动车组的乘坐舒适性和优化隔音降噪设计，对高速动车组噪声源进行研究分析，介绍了高速动车组典型位置客室内噪声水平，分析了不同速度级下噪声的主要来源，指出高速动车组运行时的主要声源来自于轮轨噪声和气动噪声，当以速度200 km/h 运行时客室内部主要噪声源来自于轮轨噪声，而随着速度级的提高，气动噪声的作用逐渐突显，当以速度300 km/h 运行时气动噪声逐渐成为主导。

Abstract

To improve riding comfort and optimize noise insulation design for high-speed EMUs, the noise source was analyzed, and noise value of high-speed EMUs typical position passenger room was introduced. Noise source under different speed was discussed and indicated mainly from wheel-track noise and pneumatic noise. When the speed of vehicle was under 200 km/h, noise in the passenger room was from wheel-track noise; with the vehicle speed increasing, the pneumatic noise effect was gradually highlighted and became the primary when the speed reached 300 km/h.
