Spatial multi-direction viscoelasticity-shape memory alloy damping system
The invention discloses a spatial multi-direction viscoelasticity-shape memory alloy damping system. The spatial multi-direction viscoelasticity-shape memory alloy damping system comprises an annular inner cylinder, an arc-shaped middle plate, an arc-shaped outer plate, a viscoelasticity material layer, a shape memory alloy rope and a force transmission connecting unit; the plurality of arc-shaped middle plates and the plurality of arc-shaped outer plates are arranged on the outer side of the annular inner cylinder from inside to outside, and viscous-elastic material layers are arranged between the annular inner cylinder and the arc-shaped middle plates and between the arc-shaped middle plates and the arc-shaped outer plates; a plurality of shape memory alloy ropes are arranged in the annular inner cylinder, and the two ends of each shape memory alloy rope penetrate out and are fixed to the outer surface of the arc-shaped outer plate; the outer surfaces of the arc-shaped outer plates are symmetrically connected with the plurality of force transmission connecting units with the annular inner cylinder as the center axis, and the outer ends of the force transmission connecting units and the two ends of the annular inner cylinder are connected with a building. The spatial multi-direction viscoelasticity-shape memory alloy damping system has the technical advantage of having a good damping effect on vibration in any direction in space, meanwhile, the damping frequency domain of a damper is greatly widened, and the spatial multi-direction viscoelasticity-shape memory alloy damping system has good deformation resistance and recoverability.
一种空间多方向粘弹性‑形状记忆合金减震系统，包括环形内筒、弧形中板、弧形外板、粘弹性材料层、形状记忆合金绳、传力连接单元；环形内筒外侧由内向外布置有多个弧形中板、多个弧形外板，环形内筒与弧形中板之间、弧形中板与弧形外板之间设置有粘弹性材料层；环形内筒内设置有多根形状记忆合金绳，形状记忆合金绳两端穿出并固定在弧形外板外表面；弧形外板外表面以环形内筒中心轴对称连接有多根传力连接单元，传力连接单元外端以及环形内筒两端用以连接建筑物。本发明具有对空间任意方向振动均具有良好减震效果的技术优点，同时大幅度拓宽了阻尼器的减震频域，并且具有良好抵抗变形和可恢复的能力。
