摘要:
介绍了实测的高速动车组在不同运行速度、不同线路形式、不同运行方向、不同升弓车厢条件下客室内的噪声和声源特性,分析了不同运行里程阶段的车辆以相同速度运行时客室内噪声的演变规律。研究结果可为高速动车组减振降噪工作的开展提供科学依据。
Abstracts:
The total value and noise source characteristics of the high-speed EMU interior noise under circumstances of different speed grades, different railway lines, different running direction and different passenger cars with rising pantograph were introduced. The evolution pattern at different operation mileage phase was analyzed. The research results can provide scientific reference for high-speed EMU vibration and noise reduction.
