Multidirectional tuning electromagnetic energy dissipating and vibration reducing device

Abstract

The invention discloses a multi-dimensional tuning electromagnetic energy consumption and vibration reduction device, which comprises an outer box and an inner box. The outer box is provided with a plurality of small balls, and the inner box is arranged on the small balls to ensure its It can move freely in the horizontal direction; and the two sides of the inner box are connected with the inner side wall of the outer box through electromagnetic dampers, and a magnet is arranged on the inner top and inner bottom of the inner box, and the top of the inner box A spring pendulum is suspended, and the spring pendulum is located in the magnetic space formed by the magnet, and its swing can cut the magnetic induction line; the outer side wall of the outer box can move along the guide rail under the action of an external force through the slider, and the slider It is connected with a translational rack, and the translational rack moves with the slider, driving the rotating gear meshed with it to rotate, and the rotating gear drives an inner core to rotate, and the inner core is installed on the inner wall with magnetic poles In the outer cylinder, a coil is wound on the inner core, and the inner core rotates to cut the magnetic induction line, thereby forming an eddy current damper.

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...
