Magnetorheological memory alloy composite energy dissipation seismic reduction and isolation device
The invention discloses a magnetorheological memory alloy composite energy dissipation seismic reduction and isolation device. The device comprises a cylindrical shell, wherein the shell comprises a side wall, a top cover and a bottom cover; an upper screw penetrating through the top cover is arranged in the center of the top cover, the portion, located in the shell, of the upper screw is sleeved with an upper nut, and an upper flywheel is connected to the upper nut; a lower screw penetrating through the bottom cover is arranged in the center of the bottom cover, the portion, located in the shell, of the lower screw is sleeved with a lower nut, and a lower flywheel is connected to the lower nut; a cylindrical first memory alloy net ring is arranged between the upper flywheel and the lower flywheel; and a magnet exciting coil which is gradually increased from the middle to the two ends is wound around the side wall of the shell, and the shell is filled with magnetorheological fluid. According to the magnetorheological damping force energy dissipation principle, the electromagnetic damping phenomenon and the memory alloy net deformation energy dissipation mechanism, the device has good seismic reduction and isolation energy dissipation capacity, and damage caused by a seismic load to a comprehensive pipe gallery is reduced.
本发明公开了一种磁流变记忆合金复合耗能减隔震装置，包括圆柱形的壳体，壳体包含侧壁、顶盖和底盖；顶盖中心设置有贯穿顶盖的上螺杆，处于壳体内部的上螺杆套设有上螺母，上螺母上连接有上飞轮；底盖中心设置有贯穿底盖的下螺杆，处于壳体内部的下螺杆上套设有下螺母，下螺母上连接有下飞轮；上飞轮和下飞轮之间设置有圆环柱形的第一记忆合金网圈；壳体的侧壁外缠绕有从中部向两端逐渐递增的励磁线圈，壳体内填充有磁流变液。本发明利用磁流变阻尼力耗能原理、电磁阻尼现象以及记忆合金网形变耗能机理，使本装置具有良好的减隔震耗能能力，减小了地震荷载对综合管廊破坏的作用。
