Abstract

The utility model discloses a kind of High Damping Performance device with bending resistance, including damper, the damper both ends are hinged with ring flange, some dampers of annular array are put centered on the ring flange center of circle, one support column of rigid connection on the ring flange center axis at both ends, spring is arranged with the damper, two of the spring is extended on the damper connecting bar.The utility model provides the additional damping of higher compared with conventional damper;Support column and spring provide additional stiffness so that damper integrally has good bending resistance, can bear multidimensional internal force caused by Complicated Loads.

Description

A kind of High Damping Performance device with bending resistance
Technical field
The utility model belongs to vibration control technology field, is related to damper field, and in particular to one kind has bending resistance energy The High Damping Performance device of power, can be applied to the control of large span spatial structure multidimensional vibration reduction.
Background technology
With the development of industrial technology and the raising of educational level, people propose building span the requirement of higher, greatly Span spatial structures come into being and are developed rapidly, become the hot spot of structural engineering field.Large-span space structure is on ground Structural dynamic response under the effects such as shake, high wind is strong.How to reduce the dynamic response of structure, improve antidetonation, the wind resistance of structure Ability and performance is combated a natural disaster, so that building has safety and beauty concurrently and becomes current urgent problem to be solved.Traditional antidetonation Method is to improve the rigidity of structure, by the energy dissipation capacity of structure itself to absorb wind shake, rain shakes, ambient vibration and geological process The energy Deng caused by, but this certainty with the damage of structure division component or is destroyed as cost, and this is uneasy to a certain extent It is entirely and unreasonable.Therefore, to overcome traditional anti-shock methods the defects of, structural vibration control technology are gradually risen, damper It is widely used in the antidetonation vibration damping of modern civil engineering building.Damper vibration damping device on the market is only capable of at present The tension and compression effect in axle power direction is resisted, is simply possible to use in the antidetonation vibration damping of supporting member in structure, and be mainly used in high-rise and super Skyscraper;It is different from the supporting member in high-rise, super-high building structure, large-span space structure load action direction it is more The multi-dimensional nature of dimension property and structural internal force, causes structural elements to be generally under moment of flexure-axle power multidimensional internal force compound action, only has The damper for having resistance axle power ability will can not achieve the oscillation damping and energy dissipating of complicated applied force status means, not be suitable for long-span space knot Structure.Current existing damper vibration damping device is difficult the vibration control requirement for meeting large-span space structure.
Utility model content
The purpose of the utility model is to overcome above-mentioned background technology there are the defects of, there is provided it is a kind of with bending resistance High Damping Performance device, has good bending resistance and anti-axis tension and compression ability on the premise of high additional damping is provided, so as to Multidimensional internal force caused by Complicated Loads is enough born, reaches the effect that multidimensional vibration reduction is carried out to large-span space structure.
The technical solution of the utility model:A kind of High Damping Performance device with bending resistance, including damper, the resistance Buddhist nun's device both ends are hinged with ring flange, and some dampers of annular array, the institute at both ends are put centered on the ring flange center of circle One support column of rigid connection on ring flange center axis is stated, is arranged with spring on the damper, two of the spring extends to described On damper connecting bar.
The support column is made of any of which in mild steel, lead, rubber or shape memory alloy material.
The shape of the support column is any in cylinder, pipe, square column or square tube.
The damper number n is the even number of n >=4.
The spring is helical spring.
The damper is viscous damper.
The viscous damper is replaced by viscoelastic damper.
The viscous damper is replaced by the damper based on magnetostriction materials or shape memory alloy material.
Compared with prior art, the utility model has the advantage that:The utility model is realized to be set in smaller space The damper of multiple annular arrays, compared with the additional damping that conventional damper provides higher;Support column and spring provide additional firm Degree so that damper integrally has good bending resistance, can bear multidimensional internal force caused by Complicated Loads;Structure letter It is single, easy for construction, suitable for large-span space structure.
Brief description of the drawings
Fig. 1 is the 3-D solid structure schematic diagram of the utility model;
Fig. 2 is the floor map (top view, bottom view are consistent with this figure) of the utility model;
Reference numeral:1st, ring flange;2nd, support column;3rd, spring;4th, damper;5th, connecting rod.
Embodiment
The utility model is further described below by specific embodiments and the drawings.The embodiment of the utility model It is to preferably make those skilled in the art more fully understand the utility model, does not make any limit to the utility model System.
As illustrated in fig. 1 and 2, a kind of High Damping Performance device with bending resistance of the utility model, including damper 4, this The preferred viscous damper of embodiment, the viscous damper can use viscoelastic damper to replace, can also use with magnetostriction Damper based on material or shape memory alloy material is replaced, and it is several that the damper 4 is not limited to the above, can also be it The damper of his type;4 both ends of damper are hinged with ring flange 1, and annular array is put centered on 1 center of circle of ring flange Some dampers 4, for meet multi-form, different size large-span space structure vibration damping demand, damper 4 Number n is the even number of n >=4, and the number n of the present embodiment damper 4 is 4, and rigid connection one supports on 1 central shaft of the ring flange at both ends Column 2, the support column 2 are made of any of which in mild steel, lead, rubber or shape memory alloy material, the support column 2 Shape is any in cylinder, pipe, square column or square tube, can also be other symmetrical structures;In the utility model, support column 2 play a part of to increase the rigidity of structure, are arranged with spring 3 on the damper 4,3 preferred helical spring of the present embodiment spring is spiral Spring is simple to manufacture, is widely used, and during applied to the present apparatus, higher rigidity, bullet are capable of providing on the premise of lighter weight Spring 3 or ring spring, can also be butterfly spring, and the spring 3 can increase the additional damping of damper and add firm Degree, two of the spring 3 is extended on 4 connecting rod 5 of damper.
It should be appreciated that embodiment and example discussed herein simply to illustrate that, to those skilled in the art For, it can be improved or be converted, and all these modifications and variations should all belong to the appended claims for the utility model Protection domain.
