电力机车司机室减振降噪设计

Research of the Vibration and Noise Reduction for Electric Locomotive Cab

对国内外机车司机室振动和噪声的研究现状进行了回顾,从理论上对影响司机室振动和噪声的各种因素进行了分析和研究,重点对双层隔音结构设计、密封结构设计计算、吸声材料及结构、减振设计等进行分析,为司机室结构的减振降噪设计提供理论依据和设计建议。

This paper undertakes a review of the status of the study of domestic and foreign locomotive cab vibration and noise. The paper theoretically analyzes and studies various factors affected on the drive＇s cab vibration and noise.The study mainly focuses on doubledeck noise isolation design, sealing construction design and calculation, sound absorbing material and construction, vibration damping and so on. It not only provides the principle proof, but also has the guidable meaning for the vibration and noise reduction in cab structure design.
