Steel rail damping dynamic vibration absorption device
The invention provides a steel rail damping dynamic vibration absorption device which comprises at least two supporting pieces fixed to a steel rail. The device further comprises at least one connecting rod piece which is arranged in the direction parallel to the steel rail and is used for communicating the supporting pieces and a mass unit in a rigid direct connection mode or an elastic layer flexible indirect connection mode to form a bridge frame and a channel for transmitting exciting force, and at least one elastic layer which at least separates two of the connecting rod piece, the supporting pieces and the mass unit; the elastic layer is arranged at the joint of the supporting pieces and the connecting rod piece and/or the joint of the connecting rod piece and the mass unit, and theconnecting rod piece is at least partially embedded into the elastic layer. According to the steel rail damping dynamic vibration absorption device, the purpose of eliminating railway operation potential safety hazards from the source is achieved, the maintenance cost can be reduced, interference of rail maintenance construction on normal operation is reduced, and the operation efficiency is improved.
本发明提供了一种钢轨阻尼动力吸振装置，包含至少两个支撑件，支撑件固定在所述钢轨上；至少一个以相对于钢轨平行方向布置的连接杆件，连接杆件将支撑件及质量单元两者，以刚性直接连接或弹性层柔性间接连接的方式贯通起来，形成激励力传递的桥架及通道；至少一个弹性层，弹性层至少将连接杆件、支撑件、质量单元三者之中的两者分隔开来；其中，所述弹性层设置在支撑件与连接杆件的连接处和/或连接杆件与质量单元的连接处，所述连接杆件至少部分嵌入所述弹性层中。本发明所述的钢轨阻尼动力吸振装置，不仅达到从源头上消除铁路运行安全隐患的目的，还可降低了维护成本，减少轨道维护施工对正常运营的干扰，提升营运效率。
