Abstract
The utility model provides a harmonious attenuator of quality based on symmetric combination formula air spring, the harmonious attenuator of this quality include air spring I, quality piece, piston, air spring II, cylinder and additional chamber, and with air spring I and II symmetric placements of air spring, the two is the same, connect through the piston rod, and the tie point department of piston rod sets up the quality piece, air spring I and air spring's II the cylinder additional chamber the same with the volume respectively communicates with each other, additional chamber 7 through its inside atmospheric pressure, temperature, volumes of control system regulation control to the above -mentioned parameter that keeps two additional chambers 7 is the same. Elastic element's rigidity adjustable function is realized to the harmonious attenuator of this quality through the above -mentioned parameter of control, because the air flow has damping characteristic, can add some controllable air damping devices, directly changes TMD's damping characteristic.
Description
Technical field
The utility model is related to a kind of tuned mass damper (Tuned Mass based on Symmetric Composite formula air spring
Damper, TMD), using Symmetric Composite formula air spring as the design of flexible member.
Background technology
Symmetric Composite formula air spring be it is a kind of by two identical symmetrically placed combinations of air spring minute surface one
Rise, overall two ends are fixed in a structure, two junctions of spring are the hard point of spring, you can realize the point and consolidate
Elastic connection between fixed end.The hard point of this spring offsets along that direction and rigidity hardening characteristics is all presented, and this
Plant hardening phenomenon symmetrical on spring hard point initial position, irrelevance is bigger, and linear Stiffness is stronger.And Symmetric Composite formula
Air spring can be controlled to change the mechanical characteristic of spring, meet some specific requirements.
Tuned mass damper (TMD) is that one kind adjusts to main structure itself vibration frequency, changes mesomerism
Characteristic, to reach the device of cushioning effect.TMD is mainly used in the places such as skyscraper, bridge, mass spring and main knot
Structure is connected, and when main structure produces vibration because of the effect of the external force such as earthquake or wind-force, the device also occurs to swing accordingly or turn round
Rotational oscillation is moved, and the purpose of main structure damping is made so as to reach.It can also be used in other needs the place of damping.
TMD is developed into and is derived many types today, is mostly passive-type, once i.e. its frequency response model of installation
Enclose, the characteristic such as damping ratio immobilizes, semi- active control type (Semi-active Tuned Mass Damper, SATMD) it is big
Mostly it is to be realized by adjusting damped coefficient or spring rate.
In sum, it is necessary to a kind of TMD systems of application Symmetric Composite formula air spring are proposed, by adjusting air bullet
Spring realizes the optimization of TMD dampings.
Utility model content
TMD system reality of the utility model primarily directed to application Symmetric Composite formula air spring (hereinafter referred to as " spring ")
The function of existing damping effect optimization.
The technical solution of the utility model：
A kind of tuned mass damper based on Symmetric Composite formula air spring, including air spring I 2, mass 3, work
Plug 4, air spring II 5, cylinder 6 and additional chamber 7, air spring I 2 and air spring II 5 is symmetrically placed, and the two is identical, leads to
Piston rod connection is crossed, mass 3 is set at the tie point of piston rod；The cylinder 6 of air spring I 2 and air spring II 5 respectively with
Volume identical additional chamber 7 is communicated；Described additional chamber 7 adjusts air pressure, temperature and appearance of its inside of control by control system
Product, and keep the above-mentioned parameter of two additional chambers 7 identical.
Described air spring I 2 and air spring II 5 is all telescopic air spring or is all gasbag-type air spring,
Accompanying drawing 1 is only by taking telescopic air spring as an example.
The beneficial effects of the utility model：
1. the volume of auxiliary chamber is bigger, (analysis below is all with this standard) spring rate in the case that other specification is constant
It is non-linear weaker, the spring rate reduction in the case where keeping mass amplitude constant equivalent to TMD, vice versa；
2. the air pressure inside of inactive state is bigger, and spring integral rigidity is bigger, non-linear stronger, is keeping mass amplitude
Spring rate increase in the case of constant equivalent to TMD, vice versa；
3. internal air temperature is higher, and situation is identical with result 2, and vice versa；
4. because air flow has damping characteristic, some controllable air damping devices can be added, directly change TMD
Damping characteristic.
Brief description of the drawings
Fig. 1 is a kind of tuned mass damper schematic diagram based on Symmetric Composite formula air spring.
In figure：1 main structure；2 air springs I；3 masses；4 pistons；5 air springs II；6 cylinders；
7 additional chambers.
Specific embodiment
Below in conjunction with accompanying drawing and technical scheme, specific embodiment of the present utility model is further illustrated.
Air spring I 2 and air spring II 5 are fixedly connected with main structure 1 respectively, air spring I 2 and air spring II 5
Piston rod be fixedly connected with mass 3, constitute basic TMD systems.Cause to solve the change of the vibration frequency of main structure 1
The problem that TMD damping effects decline, by adjusting air spring I 2, the volume size of additional chamber 7 of air spring II 5, internal gas
Damping size when body pressure and temperature, gas flow, so as to adjust the integral rigidity of Symmetric Composite formula air spring, damping spy
Property, realize the function of control TMD parameter optimizations.
