Ultralow-frequency tuned mass inertial damper
The invention relates to an ultralow-frequency tuned mass inertial damper, and relates to the technical field of damping vibration attenuation devices, the ultralow-frequency tuned mass inertial damper comprises a fixed box and a damper body arranged in the fixed box, the damper body comprises a spring, a damping piece, a mass block and an inertial container, and one end of the spring and one end of the damping piece are fixed to the top of the fixed box; the mass block is fixedly connected with the other end of the spring and the other end of the damping piece and rotationally connected with a rotating shaft. The inerter comprises a rack, a flywheel and a gear, the rack is vertically fixed in the fixed box, the flywheel is fixedly sleeved at one end of the rotating shaft, the gear is fixedly sleeved at one end, close to the flywheel, of the rotating shaft, and the gear is located on the side of the rack and can be meshed with the rack; the mass block can be driven by the spring to move up and down and can drive the flywheel and the gear to move up and down through the rotating shaft, and the gear can be meshed with the rack and drive the flywheel to rotate around the rotating shaft while moving up and down. The static elongation of the spring can be reduced, the frequency and the initial friction resistance can be reduced, and ultralow-frequency structure vibration reduction is achieved.
本申请涉及一种超低频调谐质量惯质阻尼器，涉及阻尼减振装置技术领域，包括固定箱及设于固定箱内的阻尼器，阻尼器包括弹簧、阻尼件、质量块和惯容器，弹簧和阻尼件的一端分别固定于固定箱的顶部，质量块分别与弹簧、阻尼件的另一端固定连接，并转动连接有一转轴；惯容器包括齿条、飞轮和齿轮，齿条竖直固定于固定箱内，飞轮套设固定于转轴的一端，齿轮套设固定于转轴靠近飞轮的一端，齿轮位于齿条的侧方并可与齿条啮合，质量块在弹簧的带动下可进行上下运动并可通过转轴带动飞轮和齿轮上下运动，齿轮在上下运动的同时可与齿条进行啮合运动并带动飞轮绕转轴旋转。本申请不仅可降低弹簧静力伸长量，还可降低频率和初始摩阻，实现超低频结构减振。
