Multidirectional tuning electromagnetic energy dissipating and vibration reducing device

Abstract

The invention discloses a multidirectional tuning electromagnetic energy dissipating and vibration reducing device which comprises an outer box and an inner box. A plurality of balls are arranged inside the outer box. The inner box is arranged on the balls so as to ensure free movement in the horizontal direction; the two sides of the inner box are connected with the inner side wall of the outer box through electromagnetic dampers, the inner top and the inner bottom of the inner box are each provided with a magnet, a spring pendulum is suspended to the top of the inner box and located inside the magnetic space formed by a magnet, and oscillation of the spring pendulum can cut magnetic induction lines; the outer side wall of the outer box can move along a guide rail under the external force action through a sliding block, and the sliding block is connected with a translation rack, the translation rack moves along with the sliding block and drives a rotating gear meshed with the translation rack to rotate, the rotating gear drives an inner core to rotate, the inner core is installed in an outer cylinder with a magnetic pole on the inner wall, a coil is wound around the inner core, the inner core rotates to cut the magnetic induction lines, and then an eddy current retarder is formed.

Description

technical field [0001] The invention belongs to the field of vibration reduction control of towering structures, and in particular relates to a multi-dimensional tuning electromagnetic energy consumption vibration reduction device. Background technique [0002] my country is a country where wind disasters and earthquake disasters occur relatively frequently. Because of its large slenderness ratio and high height, towering structures belong to buildings where lateral load plays a major role. Compared with ordinary building structures, high-rise structures have low horizontal stiffness, are sensitive to wind loads and earthquakes, and are prone to large dynamic responses, especially under the action of strong winds or strong earthquakes, they are prone to damage or even collapse, causing huge economic losses. . Therefore, it has become a hot topic in the field of structural engineering to improve the wind and earthquake resistance of towering structures, reduce their vibratio...
