Embodiment 1

[0028] see Figure 1 to Figure 7 , the three-dimensional tuned mass damper with a card slot is characterized in that it includes an outer sleeve 1, an upper card plate 2, an upper card slot inner ring 3, a horizontal spring 4, an upper adjustable mass block 5, and an upper card slot outer ring 6. Horizontal damper 7, outer ring 8 of lower slot, lower adjustable mass 9, inner ring 10 of lower slot, vertical spring 11, vertical damper 12 and outer bottom plate 13. The horizontal spring (4) and the horizontal damper 7 are evenly distributed in the circumferential direction, and the two ends are arranged radially and connected with the outer sleeve 1 and the upper clamping groove outer ring 8 bolts respectively; the upper clamping groove outer ring 6 is connected with the upper clamping groove. The inner ring 3 of the slot is in smooth contact; the inner ring 3 of the upper slot is connected with the upper adjustable mass 5 by bolts; the outer ring 6 of the upper slot is in smooth...

Embodiment 2

[0030] This embodiment is the same as Embodiment 1, and the special case is as follows: the outer ring 6 of the upper draw-in slot is an outer ring with four arc-shaped cards in vertical directions and four vertical direction arc cards on the inner ring 3 of the upper draw-in slot. Curved card slot smooth contact mating. There are two annular grooves on the inner wall of the lower card slot outer ring 8 , which are smoothly mated with the annular protruding rings on the outer wall of the lower card slot inner ring 10 . Four vertical springs 11 are evenly distributed around the circumference and a vertical damper 12 is located at the center.

[0031]

Embodiment 3

[0033] Such as figure 1 As shown, the three-dimensional tuned mass damper device with a card slot includes an outer sleeve 1, an upper card plate 2, an inner ring 3 of an upper card slot, a horizontal spring 4, an upper adjustable mass block 5, and an outer ring 6 of an upper card slot , the horizontal damper 7, the outer ring of the lower slot 8, the lower adjustable mass block 9, the inner ring of the lower slot 10, the vertical spring 11, the vertical damper 12, and the outer base plate 13.

[0034] Such as figure 2 As shown, the overall device of the outer sleeve includes an outer sleeve 1 , an upper clamping plate 2 , and an outer bottom plate 13 .

[0035] Such as image 3 and Figure 4 As shown, the internal device includes an upper slot inner ring 3, a horizontal spring 4, an upper adjustable mass block 5, an upper slot outer ring 6, a horizontal damper 7, a lower slot outer ring 8, and a lower adjustable mass Block 9, the inner ring 10 of the lower part of the ca...

Abstract

The invention relates to a three-dimensional tuned mass damper device with a clamping groove. The three-dimensional tuned mass damper device comprises an outer sleeve, an outer bottom plate, an upper clamping plate, an upper tunable mass block, a lower tunable mass block, an upper clamping groove outer ring, an upper clamping groove inner ring, a lower clamping groove outer ring, a lower clamping groove inner ring, a horizontal spring, a vertical spring, a horizontal damper and a vertical damper. The mass of the dampers is adjusted by adjusting the number of the mass blocks so as to achieve the frequency adjustment of the dampers; and due to a three-way limiting device, the frequencies in different directions are not influenced and the purpose of three-dimensional shock/vibration absorption is achieved. The three-dimensional tuned mass damper device can control the influence of the air vibration effect on the structure and reduce the effect of an earthquake on the structure, and can be used for vibration control of building structures such as bridge constructions, ocean platforms, large-span cantilever structures and the like.

Description

technical field [0001] The invention relates to a three-dimensional tuned mass damper with a slot, and belongs to the technical fields of wind vibration control, shock resistance and shock absorption. Background technique [0002] Structural passive control is the earliest and most widely used vibration control method at home and abroad. Judging from the current situation, many achievements have been made in theory and application of structural passive control. Passive control does not require external energy. Its principle is to install seismic isolation or other energy dissipation devices in certain parts of the structure, and reduce the seismic response through its own energy consumption. Due to the advantages of low cost, simple structure, easy maintenance and no need for external energy support, passive control has attracted extensive attention in the field of civil engineering and is widely used in practical engineering. Passive control mainly includes base isola...
