Adjustable ultralow-frequency vertical eddy current tuned mass damper (TMD)
The invention discloses an adjustable ultralow-frequency vertical eddy current tuned mass damper (TMD) and belongs to the technical field of structural vibration control. The ultralow-frequency vertical eddy current TMD comprises a base, a rigid framework, a rigid framework cross beam, a mass block position adjusting rod, a first nut, a second nut, a mass block, a permanent magnet fixed plate, a permanent magnet set, a conductor copper plate, a magnetic conductive steel plate, a first linear guide rail, an inerter-damping system, a coil spring and a second linear guide rail. The actual physical mass of the TMD is reduced by the inerter-damping system, and the problem of net elongation of a spring of an ultralow-frequency vertical eddy current is too large is solved; the device frequency isadjusted continuously by adjusting the distance between the mass block and a fixed reamer; and an eddy current damping technology is adopted, and the device damping is adjusted continuously by adjusting the distance between the permanent magnet set and the conductor copper plate. In addition, the device has the advantages of simple assembly, easy-to-adjust frequency and damping, good durability and the like.
