Floating slab track vibration isolation system based on tuned viscous mass damper
The invention provides a floating slab track vibration isolation system based on tuned viscous mass dampers, and belongs to the technical field of track vibration isolation equipment.The floating slab track vibration isolation system comprises a steel rail, a track slab, a fastener, a horizontal limiting device, a shear hinge, a vibration isolator, an upper cover, the tuned viscous mass dampers, a base and a sleeve; the upper cover, the tuning viscous mass damper, the base and the sleeve form an inerter vibration isolation system; the track plate is arranged below the steel rail, and the track plate is fixedly connected with the steel rail through the fastener; the horizontal limiting devices are arranged on the two sides of the track plate. And the shear hinge is used for connecting the track plate with another track plate. According to the floating slab vibration isolation system based on the inerter mechanism, optimal design can be carried out according to different working conditions and the structural form of the floating slab track, and the design result is more ideal; the device has a simple mechanism form and can work independently, so that the cost is relatively low; prefabrication is achieved, and maintenance and replacement can be facilitated on the engineering site.
本发明提供一种基于调谐粘滞质量阻尼器的浮置板轨道隔振系统，属于轨道隔振设备技术领域，包括浮置板轨道系统，包括钢轨、轨道板、扣件、水平限位装置、剪力铰、隔振器、上盖、调谐粘滞质量阻尼器、底座以及套筒；上盖、调谐粘滞质量阻尼器、底座以及套筒组成惯容隔振系统；轨道板设置在钢轨下方，且轨道板与钢轨通过所述扣件固定连接；水平限位装置设置在轨道板的两侧；剪力铰用于将轨道板与另一轨道板连接。本发明所设计的基于惯容机构的浮置板隔振系统，可根据不同工况条件和浮置板轨道的结构形式进行最优化的设计，设计结果更加理想；具有简明的机构形式，且可独立工作，因此具有较低的成本；具有可预制性，在工程现场可以方便检修更换。
