摘要
运用多通道噪声测试与分析系统,对运行中的铁路客车进行了多点同步车内噪声测试和分析,得出了在不同工况和不同运行速度时的车内噪声的现状和分布规律,确定出车内噪声发生的主频带,对既有线铁道车辆和将来的高速铁道车辆进行防噪降噪设计具有较高的参考价值。
In the paper, through measurements of interior noise of existing railway vehicles in china, studies propagation routes and distributing characteristics, puts forward to the distributing rules of interior noise in different statuses and speeds, gets the main frequency band , it benefits to noise abatement and reduction design of existing and high-speed railway vehicles.
