浅谈电力机车司机室降噪设计

Discussion on noise reduction design of electric locomotive cab

机车的振动和噪声是造成司乘人员疲劳的主要因素之一,司机室噪声主要来源于机械间内设备的运转产生噪声和结构、设备振动而辐射出来的结构振动噪声。从理论上分析了结构及材料对噪声的影响,提出了目前常用的隔声降噪材料和测试噪声的方法。

This paper mainly introduces the vibration and noise of the locomotive is one of the main factors causing the fatigue of drivers,and the noise of the cab mainly comes from the noise generated by the operation of equipment in the machine room and the structural vibration noise radiated by the vibration of equipment.The influence of structure and material on noise is analyzed theoretically,and the commonly used sound insulation and noise reduction materials and the methods of noise testing are put forward.
