Problems solved by technology

However, in the actual engineering application of the traditional tuned mass damper, the degree of vibration damping effect depends on whether its natural vibration frequency is tuned to the main structure, and it cannot adjust its dynamic characteristics in real time according to the specific external excitation conditions and structural responses. , and thus cannot guarantee the best damping effect

Abstract

The invention discloses a semi-active magneto-rheological tuned mass damper. The semi-active magneto-rheological tuned mass damper comprises a barrel body; a connection block is arranged in a bottom plate of the barrel body; and a working cylinder is fixed to the connection block. Separation plates are arranged in the working cylinder, and the working cylinder is divided into a center cavity, damping cavities and side cavities. The center cavity is internally provided with a mass block capable of horizontally moving in the axis direction of the axis of the working cylinder. The center of the mass block is provided with a groove and a rolling bearing, and the periphery of the mass block is connected with piston rods capable of sliding along the rolling bearing. The damping cavities are internally provided with pistons, and the pistons are fixedly connected to the piston rods. The piston rods penetrate through holes reserved in the partition plates, extend into the side cavities and areconnected with one ends of springs in the side cavities. The other ends of the springs are fixedly connected into the working cylinder. The damping cavities are filled with magneto-rheological fluid,and powered-on coils are wound around the damping cavities. The powered-on coils are connected with an induction control device inside the barrel body.

Description

technical field [0001] The invention belongs to the field of vibration control of civil engineering, in particular to a semi-active magneto-rheological tuned mass damper, which is mainly used to control the vibration response of high-rise buildings and towering structures. Background technique [0002] With the advancement of science and technology and the development of society, modern high-rise buildings and high-rise structures continue to appear, and develop in a higher and softer direction. However, under the action of dynamic loads such as wind or earthquakes, the structure is prone to large lateral Vibration and deformation, even beyond the permissible comfort requirements. In recent years, in order to reduce the vibration response of structures, installing reasonable and effective damping systems in high-rise buildings and high-rise structures has received more and more attention. [0003] Tuned mass damper (Tuned mass damper) is a mature vibration reduction and ene...
