Embodiment

[0017] Such as figure 1 with figure 2 As shown, the horizontal frequency modulation mass damper includes wall seat 1, lock nut 2, spring 3, mass block 4, damping liquid tank 5, steel ball 6, damping liquid 7, and screw rod 8. If the outermost side is wall seat 1 The two wall bases 1 are connected by screw rods 8, and the joints are tightened with lock nuts 2. The damping fluid tank 5 is welded on the two screw rods 8 at the bottom of the wall base 1, and the screw rod 8 at the upper part of the wall base 1 plays a connecting role. The steel ball 6 is covered with the damping liquid tank 5, the damping liquid 7 is filled with the damping liquid tank 5, the mass block 4 is placed on the steel ball 6, and is located in the center of the two wall seats 1, and the spring 3 is connected Mass block 4 and two wall seats 1.

[0018] Working principle of the present invention is:

[0019] In the present invention, the steel ball 6 is arranged in the damping liquid tank 5 to realize ...

Abstract

The invention relates to a horizontal frequency adjusting mass damper. The horizontal frequency adjusting mass damper comprises wall bases, locking nuts, springs, a mass block, a damping fluid box, steel beads, damping fluid and a screw rod. The wall bases are located on the outermost sides, the two wall bases are connected through the screw rod, and the joints are fastened by the locking nuts. The damping fluid box is welded to the upper portion of the screw rod connected with the lower portions of the wall bases, the bottom of the damping fluid box is fully paved with the steel beads, and the damping fluid box is filled with the damping fluid. The mass block is placed on the upper portions of the steel beads, and the mass block is connected with the wall bases on the two sides through the springs. The horizontal frequency adjusting mass damper has the beneficial effects that the horizontal frequency adjusting mass damper packs the damping fluid into the damping fluid box, the steel beads are placed in the box, so that the damping fluid achieves the damping effect, and meanwhile can work as lubricating oil of the steel beads, and the friction force when the mass block moves is reduced. The structure is convenient to machine and mount, and the friction force is smaller.

Description

technical field [0001] The invention relates to an energy dissipation shock absorber of a building structure, in particular to a horizontal frequency modulation mass damper. Background technique [0002] The FM mass damper is a kind of structural passive vibration reduction control system. It consists of a main structure and a substructure attached to the main structure. The substructure includes a mass system, a support system (spring and damper), and is generally suspended or supported on the structure. [0003] The working mechanism of the FM mass damper is "dynamic braking", that is, the movement of one mass block is used to control or weaken the movement of another mass block. By adjusting the dynamic characteristics, its natural vibration frequency is as close as possible to the fundamental frequency of the main structure. Or excitation frequency, when the main structure is excited by the external load and vibrates, the frequency-modulated mass damper will generate an...
