Bidirectional variable-curvature variable-friction pendulum type tuned mass damper
The invention provides a bidirectional variable-curvature variable-friction pendulum type tuned mass damper. The supporting seat plate of the bidirectional variable-curvature variable-friction pendulum type tuned mass damper comprises a seat plate body, the seat plate body is provided with a contact face matched with a lower sliding face of a sliding block, the contact face is a concave arc face, a plurality of spherical concave faces which are in smooth connection are sequentially arranged on the contact face from bottom to top, a friction layer is arranged on each spherical concave face, and the friction layers are arranged on the spherical concave faces. The radiuses of the plurality of spherical concave surfaces are sequentially reduced from bottom to top, and the friction coefficients of the friction layers of the plurality of spherical concave surfaces are sequentially increased from bottom to top. The bidirectional variable-curvature variable-friction pendulum type tuned mass damper can provide a stable and continuous self-adaptive effect and an excellent bidirectional damping and energy dissipation effect for a controlled structure under different environmental loads, and the purpose of effectively controlling vibration of the structure in three main shaft directions under a Cartesian coordinate system at the same time through one inertial mass block can be achieved; the structure is simple, and the construction is convenient.
本发明提供了一种双向变曲率变摩擦摆式调谐质量阻尼器。本发明的双向变曲率变摩擦摆式调谐质量阻尼器的支撑座板包括座板本体，座板本体具有与滑块下滑动面相适应的接触面，接触面为凹形圆弧面，在接触面自下至上依次设有多个平滑连接的球形凹面，在每一球形凹面上设有摩擦层，多个球形凹面的半径自下至上依次减小，多个球形凹面的摩擦层的摩擦系数自下至上依次增大。本发明的双向变曲率变摩擦摆式调谐质量阻尼器能够为不同环境荷载下的被控结构提供稳定持续的自适应效果和卓越的双向减震耗能作用，可达到利用一个惯性质量块同时有效控制笛卡尔坐标系下结构三个主轴方向振动的目的，具有构造简单、施工方便等优势。
