Abstract

The invention provides an eddy current TMD (tuned mass damper) device based on horizontal bidirectional adjustment, belongs to the technical field of tuned mass dampers, and solves the problems that an existing morning adjustment mode for changing the distance between a conductor and a magnet has great uncertainty during actual installation and adjustment, and the adjustment size is difficult to control. According to the technical scheme, the device comprises a rectangular-ambulatory-plane base, a guide supporting assembly is arranged in the rectangular-ambulatory-plane base, a balancing weight is movably arranged on the guide supporting assembly, adjusting type mechanical damping assemblies are arranged on the left side and the right side of the balancing weight, and horizontal two-way adjusting eddy current damper assemblies are arranged on the front side wall and the rear side wall of the balancing weight. The horizontal bidirectional adjusting eddy current damper assembly has the beneficial effects that the different overlapping areas of the eddy current plate on the upper permanent magnet and the lower permanent magnet are adjusted, so that the damping size of the horizontal bidirectional adjusting eddy current damper assembly is rapidly adjusted.

Description

technical field [0001] The invention relates to the technical field of tuned mass dampers, in particular to an eddy current TMD device based on horizontal bidirectional adjustment. Background technique [0002] As the most widely used passive vibration damping device, tuned mass damper (TMD) has an outstanding vibration control effect on wind-sensitive structures such as super high-rise buildings and long-span bridges. TMD is generally composed of spring elements, damping elements and mass elements, and can be divided into horizontal TMD and vertical TMD according to the movement direction of mass elements. [0003] In order to realize adjustable eddy current damping, the eddy current damper type TMD generally realizes damping adjustment by changing the distance between the conductor and the magnet. Since the change of the magnetic field strength changes exponentially with the distance, changing the distance between the conductor and the magnet The adjustment method of the ...
