SELF-RESET TUNED MASS DAMPER BASED ON EDDY CURRENT AND SHAPE MEMORY ALLOY TECHNOLOGY

WIPO Patent Application WO/2021/051372

A1

The present invention discloses a self-reset tuned mass damper based on eddy current and shape memory alloy technology, and belongs to the technical field of structural vibration control. The self-reset tuned mass damper comprises a hollow cuboid, a cover plate, bolts, a mass block, a gear a, a gear b, a gear c, copper strips, permanent magnet groups, a partition plate, balls, a hinge pin, a lever, a shape memory alloy, a rotating shaft a, a rotating shaft b, a supporting steel plate and a rotating shaft c. The movement of the mass block drives the rotation of the copper strips to generate the eddy current to consume energy, by adjusting the size of the gears, the rotation of the copper strips is enlarged, small displacement of the mass block can cause the rotation of the copper strips at a large angle, and the energy consumption efficiency is greatly improved; by adjusting the ratio of long force arms to short force arms of the lever, the elongation of the shape memory alloy is enlarged, small displacement of the mass block can cause a large elongation of the shape memory alloy, and the energy consumption efficiency is high; the present invention is reasonable in design, simple in structure, convenient to install and wide in application prospect.
