Abstract
The present invention discloses a multi-dimensional eddy current tuned mass damper, which belongs to the technical field of structural vibration control. A main body of the multi-dimensional eddy current tuned mass damper is composed of two hollow cylinders, wherein an inner hollow cylinder is located in an outer hollow cylinder, ball grooves are formed in the opposite upper and lower walls of the inner and outer hollow cylinders, rolling balls are installed in the ball grooves, and the inner hollow cylinder is rotated in the outer hollow cylinder through the rolling balls; the inner hollow cylinder is provided with an inner cover plate, and the outer hollow cylinder is provided with an outer cover plate, forming a relatively closed box body structure; an orthogonal bidirectional mass element, a stiffness element and an eddy current damping element are arranged in the inner hollow cylinder, and a torsional stiffness element and an eddy current damping element are arranged between the inner hollow cylinder and the outer hollow cylinder. The multi-dimensional eddy current tuned mass damper of the present invention is not only convenient to adjust in terms of mass, stiffness and dampi…
