Lever-type inertial capacity-enhancing efficiency shape memory alloy self-resetting structural system
ActiveCN112031504BFlexible adjustment of the natural vibration periodImprove energy efficiencyProtective buildings/sheltersShock proofingClassical mechanicsShape-memory alloy
The invention provides a self-resetting structural system of a lever-type inertial capacity-enhancing shape memory alloy. The structural system includes two columns and a beam. The two columns are respectively installed at both ends of the beam to form a door-shaped frame structure; the structural system also includes Including: connecting block, the connecting block is arranged in the middle of the beam; lever, the top of the lever is movably connected with the connecting block, and the connecting block moves horizontally to drive the bar to swing; mass block, the mass block is arranged at the bottom end of the lever; rigid bracket, the lever The rotation fulcrum is set on the rigid support; the self-resetting damper is installed between the rigid support and the lever. This structural system utilizes the mass amplification effect of inertial capacity to provide a large inertia to the structural system with a small mass, thereby playing the role of flexibly adjusting the natural vibration period of the structural system; and the deformation amplification effect of the lever can significantly improve the self-resetting damping Improve the energy consumption efficiency of the device and improve its self-resetting force on the structure.
