Inerter damping system with negative stiffness shape memory alloy
The invention relates to an inerter damping system with a negative stiffness shape memory alloy, comprising: an outer cylinder, the exterior of which is closed to provide support and protection for the interior; the inerter unit is mounted in the outer cylinder and comprises a lead screw, a ball, a ball nut, a rotary mass block and a through bolt; the negative stiffness unit is connected with the inerter unit, is mounted in the outer cylinder, has a negative stiffness characteristic, and comprises a bolt, a pre-pressing spring, a spring inner connecting piece and a spring outer connecting piece; the shape memory alloy unit is connected with the inerter unit, part of the shape memory alloy unit is mounted in the outer cylinder to form an inner shape memory alloy inhaul cable group, part of the shape memory alloy unit is mounted outside the outer cylinder to form an outer shape memory alloy inhaul cable group, and each group comprises an inhaul cable formed by twisting four shape memory alloy wires. Through the combination of the outer cylinder, the inerter unit, the negative stiffness unit and the shape memory alloy unit, the deformation of the shape memory alloy is amplified, and the energy dissipation capacity of the damping system is improved.
本发明涉及一种具有负刚度形状记忆合金的惯容减震系统，包括：外筒，外部封闭为内部提供支撑与保护；惯容单元，安装于外筒内，包括丝杠、滚珠、滚珠螺母、旋转质量块和对穿螺栓；负刚度单元，与惯容单元连接，安装于外筒内，具有负刚度特性，包括螺栓、预压弹簧、弹簧内连接件和弹簧外连接件；形状记忆合金单元，与惯容单元连接，部分安装于外筒内组成内形状记忆合金拉索组，部分安装于外筒外组成外形状记忆合金拉索组，每组包括四根形状记忆合金丝材绞合而成的拉索。通过外筒，惯容单元，负刚度单元和形状记忆合金单元的组合，对形状记忆合金的变形产生放大作用，提高减震系统的耗能能力。
