地下铁道减振钢轨扣件——Cologne-Egg的初步研究

A Preliminary Study of the Rail Damper Fastener —— Cologne-Egg Used in Subway

本文对这种新型减振扣件的结构与减振机理进行了分析,并报告了它们的动力特性即动刚度和损耗因子实验情况和数据。实验结果表明,这种扣件降低振动和噪声的效果显著,可作为一种新的轨道减振措施推广应用。

The structure and mechanism of the damper fastener is analysed in this paper, and experimental results of its dynamic properties——dynamic stiffness and loss factor are also introduced. The results show that this kind of fastener can reduce vibration and noise remarkably, and might be widely used as a new vibration damper device.
