Document Type and Number:
WIPO Patent Application WO/2020/077595
Kind Code:
A1
Abstract:
A multi-dimensional electric eddy current tuned mass damper. A main body is formed by two hollow cylinders, an inner hollow cylinder (3) being located inside an outer hollow cylinder (1), a ball groove a (19) being provided on upper and lower walls of said opposite cylinders, balls a (6) being mounted in the ball groove, the inner hollow cylinder (3) rotating inside the outer hollow cylinder (1) by means of the balls a (6); the inner hollow cylinder (3) is provided with an inner cover plate (18), and the outer hollow cylinder (1) is provided with an outer cover plate (17), so as to form a relatively sealed box structure; and an orthogonal bidirectional mass unit, a stiffness unit and an electric eddy current damping unit are provided in the inner hollow cylinder (3), and a torsional stiffness unit and an electric eddy current damping unit are provided between the inner hollow cylinder (3) and the outer hollow cylinder (1).
