Rail transit vibration and noise reduction device based on damping alloy
The invention relates to a damping alloy-based rail transit vibration and noise reduction device, which comprises a lower fastening plate, the lower fastening plate is arranged on a steel rail, and at least one spring type damping alloy vibration reduction piece is arranged on the lower fastening plate or between the lower fastening plate and a track bed. The spring type damping alloy vibration attenuation pieces can be of different structures, a plurality of spring type damping alloy vibration attenuation pieces of different structures can be arranged in the same mode, and the spring type damping alloy vibration attenuation pieces of different structures can also be combined for use in different modes. Compared with the prior art, the energy consumption efficiency is high, the damping alloy can exert good damping performance under small strain, and the vibration reduction frequency band can be effectively widened; the application range is wide; the material has good mechanical properties and can be used as a structural member; and maintenance is convenient.
本发明涉及一种基于阻尼合金的轨道交通减振降噪装置，该装置包括下紧固板，所述下紧固板设置在钢轨上，在所述下紧固板上，或在所述下紧固板与轨道道床之间设置有至少一件弹簧型阻尼合金减振件。弹簧型阻尼合金减振件可以选择为不同结构，这些不同结构的弹簧型阻尼合金减振件可以采用同样的样式设置多个，也可以选择不同的样式组合使用。与现有技术相比，本发明耗能效率高，在微小应变时，阻尼合金就能发挥良好阻尼性能，且能有效拓宽减振频带；适用范围广；具有良好力学性能，可作为结构件使用；便于养护等优点。
