Inverted rail type inerter mass damper
The invention provides an inverted rail type inerter mass damper. The inverted rail type inerter mass damper comprises a base, a rolling piece, a rail piece, an inerter device and a rail fixing platform. The rolling part is rotationally installed on the surface of the base through a supporting assembly, one end of the rolling part is provided with a driving bevel gear rotating coaxially with the rolling part, the rail part is arranged at the bottom of the rail fixing platform, and the bottom of the rail part is provided with an inverted U-shaped rail matched with the rolling part so that the rail part can roll relative to the curved surface rail; the first-stage gear flywheel set comprises a driven bevel gear and a first-stage flywheel, the driven bevel gear is rotationally installed on the first shaft rod, the driven bevel gear and the driving bevel gear are in adaptive transmission, and the bottom of the driven bevel gear is fixedly connected with the first-stage flywheel and drives the first-stage flywheel to synchronously rotate around the first shaft rod. According to the mass damper, equivalent mass is provided through the inerter, the volume of the device is greatly reduced, a force-displacement relation with linear and nonlinear characteristics is obtained through track design, and the sensitivity to frequency and energy changes is improved.
本发明提供了一种倒置轨道型惯容质量阻尼器，包括：底座、滚动件、轨道件、惯容装置及轨道固定平台；滚动件通过支撑组件转动安装于底座表面，其一端设有与其同轴转动的主动锥齿轮，轨道件设于轨道固定平台底部，轨道件底部设有与滚动件适配倒置U型轨道，使其相对曲面轨道滚动，惯容装置包括多级齿轮飞轮组，一级齿轮飞轮组包括从动锥齿轮和一级飞轮，从动锥齿轮转动安装于第一轴杆上，从动锥齿轮与主动锥齿轮适配传动，从动锥齿轮底部与一级飞轮固定连接，并带动其绕第一轴杆同步转动。本发明质量阻尼器通过惯容提供等效质量，大幅减小装置体量，通过轨道设计得到具备线性和非线性特点力‑位移关系，对频率和能量变化的敏感性得到改善。
