摘要
阐述了控制卧铺动车组振动、噪声的必要性,提出了控制卧铺动车组振动噪声的基本对策,论述了卧铺动车组降噪优化设计技术,包括声源和振源的控制优化、车体结构隔声设计、内装结构避振设计、车内声学模态设计等技术。
The necessity of controlling vibration and noise of EMU sleeper train is expounded,the basic countermeasures to control the vibration and noise of EMU sleeper train are put forward.Then,the technology of the acoustic optimization design for EMU is discussed,including the optimal control of noise and vibration sources,the sound insulation design of the carbody structure and the interior structure,the acoustic modal design of the compartment and so on.
