Vibration absorber for subway vehicle base cover plate
The invention relates to the field of building vibration reduction, and discloses a vibration absorber for a metro vehicle base cover plate, the vibration absorber comprises a fixing frame, a counterweight mass block, a vibration absorption mass block and a spring assembly, the fixing frame comprises a top plate and a bottom plate located below the top plate, the counterweight mass block is detachably installed at the center position of the upper portion of the top plate, and the vibration absorption mass block is detachably installed on the bottom plate. The vibration absorption mass block is installed in the center of the lower portion of the top plate, the spring assembly is installed at the bottom of the vibration absorption mass block, one end of the spring assembly is fixedly connected with the vibration absorption mass block, and the other end of the spring assembly is fixedly connected with the bottom plate; the device further comprises a viscous damper, and the viscous damper is arranged between the top plate and the bottom plate. Through the arrangement of the multiple layers of vibration reduction structures, the vertical vibration of the cover plate structure caused in the train running process can be effectively controlled.
本发明涉及建筑减振领域，公开了一种用于地铁车辆基地盖板的吸振器，其包括固定架、配重质量块、吸振质量块及弹簧组件，所述固定架包括顶板和位于所述顶板下方的底板，所述配重质量块可拆卸安装于所述顶板的上方中心位置，所述吸振质量块安装于所述顶板下方中心位置，所述弹簧组件安装于所述吸振质量块的底部，所述弹簧组件的一端与所述吸振质量块固定连接，另一端与所述底板固定连接；还包括粘滞阻尼器，所述粘滞阻尼器设于所述顶板和所述底板之间。本发明通过多层减振结构的设置，能够有效对列车行驶过程中引起的盖板结构垂向振动进行控制。
