The utility model discloses reform transform the structural of traditional collisional damping ware, realize that inserted sheet (strikeing the piece promptly) quantity can require the increase and decrease according to the experiment to phase reaches the efficiency of damping wire nature regulation. The attenuator can be worked in the environment of various complicacies, and the inserted sheet is adjustable, and interchangeability is high, and the frequency band broad of shock attenuation scope is little to the impact of system, good reliability, economic nature advantage such as strong.
Description
Technical field
The utility model relates to a kind of linear adjustable blade inserting impact damper, especially a kind of linear adjustable dampers.
Background technology
Damper is the device of the resistance providing motion, depletion kinergety.The feature of passive vibration control does not need the external world to carry out energy input to damper separately, so it can use under the condition of very severe.
Impact damper is the one of Passive Control.Collisional damping utilizes the collision of free quality (impactor) and main system in vibration processes to control the response of main system.Utilizing damping to carry out energy-absorbing damping is not any new technology, applies various damper (or damper) already and carry out vibration damping energy dissipating in space flight, aviation, military project, firearms, automobile and other industries.After nineteen seventies, people start step by step these technology to be converted in the Structural Engineerings such as building, bridge, railway, and its development is very rapid.Particularly have five more than ten years history hydraulic pressure viscous damper, the U.S. by Structural Engineering circle accept before, experienced by a great many of experiments, close scrutiny, proves repeatedly, particularly earthquake test lengthy procedure.
Traditional impact damper adds spherical impactor in airtight cavity, and when dither, spherical impactor can constantly impact chamber wall two ends, because percussion consumes the energy of system.Therefore the size of its impact force directly determines the effectiveness in vibration suppression of damper.
Summary of the invention
The utility model will provide a kind of inserted sheet linear adjustable impact damper, for the damping size of linearizing adjustment damper.
For achieving the above object, the technical solution adopted in the utility model is: the linear adjustable impact damper of a kind of inserted sheet, there is a damper cavity, described damper cavity inside is provided with many pieces of metal impact sheets, and releasable connection between metal impact sheet and damper cavity, the outside two ends of described damper cavity are provided with the magnetic end cap for increasing metal impact sheet impact power, and metallic particles is equipped with in damper cavity inside.
Described metal impact sheet is provided with squeezing through-hole.Described magnetic end cap is electromagnet end cap, and two electromagnet end caps connect power supply respectively.
When metal impact sheet impacts, a described electromagnet end cap switches on power carrying magnetic, electromagnet end cap power-off described in another.
The beneficial effects of the utility model are:
1) damper cavity easy accessibility, impact sheet quantity is replaceable, can realize damping linear regulation.
2) compared with impact damper in the past, inside cavity has multiple impact sheet, impacts on sheet and punches, impel collision and the friction of metallic particles and metal impact sheet, and strengthen squeezing effect to realize larger power consumption, lifting damping effect.
3) carrying magnetic end cap is added at the two ends of conventional butt damper.Its carrying magnetic end cap effectively can increase the effectiveness in vibration suppression of impact damper.
Damper structure of the present utility model is simple, and damping can linear regulation, easily manufactured, adapts to various environment, damping bandwidth, little to the impact of system, good reliability, the advantages such as wear and tear little, interchangeability is high, and economy is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of metal impact sheet.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Fig. 1, shown in 2, a kind of magnetic-particle impact damper, comprises magnetic end cap 1, metal impact sheet 2, metallic particles 3, damper cavity 4.
Damper cavity 4 inside is provided with many pieces of metal impact sheets 2, and the outside two ends of damper cavity 4 are provided with the magnetic end cap 1 for increasing metal impact sheet 2 impact power, and metallic particles 3 is equipped with in damper cavity 4 inside.
Metal impact sheet 2 is provided with squeezing through-hole.Magnetic end cap 1 is electromagnet end cap, and two electromagnet end caps connect power supply respectively.When metal impact sheet 2 impacts, an electromagnet end cap switches on power carrying magnetic, another electromagnet end cap power-off.
Damper cavity 4 inside is provided with many pieces of metal impact sheets 2, when there is vibration in the external world, metal impact sheet 2 can in the concussion of damper cavity 4 inside, and collide with metallic particles 3, friction, extruding, metallic particles 3 meeting bump flow in damper cavity 4, the power consumption to vibrational system can be increased like this, to reach the effectiveness in vibration suppression to vibrational system.
The outside two ends of damper cavity 4 are provided with magnetic end cap 1, when clashing into for metal impact device, increase impact force.During metal impact device kicker magnet end cap, due to magneticaction, the impact force that it clashes into can be strengthened.
