Description
Technical field
The utility model is related to a kind of damper, especially a kind of damper based on deformed spring.
Background technology
In space industry, since there are inevitable chatters in emission process for rocket, and the space equipments such as satellite are past
Toward carrying precision instrument, therefore Payload Attach Fitting needs to install damper additional, and not vibrated destruction is loaded with protection.It is common at present
Space flight damper realizes vibration isolation as described in 201110058327.0 using metalolic network material members, the deficiency of the damper
It is that its isolation frequency is relatively narrow, needs to carry out many experiments for product to determine the parameter of metalolic network material members, cause
R＆D costs are high, the R＆D cycle is long.In addition to this, also just like the nonmetallic compound vibration-damper described in 201610344838.1,
Effectiveness in vibration suppression of the nonmetallic cushion blocking on shear direction is poor；Combined vibration-damping plate bulk, the weight that it is used are larger, the vibration damping
The production technology of device is complicated, such as needs elastic conjunction at low temperature, the material using special material or by special surface processing,
It is high-temperature alloy material GH4169 as composite damping board uses 022Cr17Ni12Mo2, limiting bush material, base's aluminium sheet is in phosphorus
Epoxy ester undercoat H062 is sprayed after sour anodization, damping column is bonded aluminium set by damping rubber column bonding by Vulcanization in aluminium set outer surface shape
At.
Utility model content
The purpose of this utility model is to provide a kind of goods-shelf type damper, fast adaptation space flight load is promoted vibration isolation
Can, reduce R＆D costs.
The technical solution of the utility model is：A kind of damper based on deformed spring, it is characterised in that cushion blocking,
Gland, bushing, damper mounting plate；
The cushion blocking is with the characteristic special-shaped compression spring of strong nonlinearity, the connection dot interlace of compression spring between layers
Distribution；
The gland is the metalwork of similar hex nut, is equipped with cylindrical step；
The bushing is the metalwork of similar outer-hexagonal bolts, and cylindrical step is equipped at nut and Stud connection；
The damper mounting plate is metal flange, and two sides is equipped with circular counter bore, and counterbore center is equipped with cylindrical hole；
Bushing, cushion blocking, mounting plate, cushion blocking, gland assemble successively according to sequence from top to bottom, bushing and gland
The inner wall of cylindrical step outer rim and cushion blocking coordinates, and the outer rim of mounting plate counterbore side wall and cushion blocking coordinates.
The utility model has the advantage of：
1. the damper of the utility model can reduce Oscillation Amplitude, by adjusting parameter, energy in larger frequency range
Enough disposable adaptations realized to most space flight load.
2. the damper of the utility model, dimension and weight is less than the comparable existing damper of performance.
3. the damper of the utility model.Rigidity is small when metal shock reducing pad has a small deformation, large deformation when big hard of rigidity
Characteristic nonlinearity rigidity can meet the needs that in-orbit vibration isolation is limited with transmitter section, exhausting section simultaneously.
4. the damper of the utility model, since there is no abrasions such as sliding frictions, service life is long, reusable.
5. the damper of the utility model, number of parts is few, assembles and using relatively simple.
6. the damper of the utility model, is all made of metal material, the operation is stable, dependable performance.With it is nonmetallic
Damper is compared, good environmental adaptability, has many advantages, such as not influenced by high/low temperature, vacuum, space radiation.

Specific implementation mode
As shown in Fig. 1,2,3,4 and 5, a kind of damper based on deformed spring, it is characterised in that cushion blocking 1, gland 2,
Bushing 3, damper mounting plate 4；
The cushion blocking 1 is with the characteristic special-shaped compression spring of strong nonlinearity, the tie point friendship of compression spring between layers
Mistake distribution；
The gland 2 is the metalwork of similar hex nut, is equipped with cylindrical step；
The bushing 3 is the metalwork of similar outer-hexagonal bolts, and cylindrical step is equipped at nut and Stud connection；
The damper mounting plate 4 is metal flange, and two sides is equipped with circular counter bore, and counterbore center is equipped with cylindrical hole；
Bushing 3, cushion blocking 1, mounting plate 4, cushion blocking 1, gland 2 assemble successively according to sequence from top to bottom, bushing 3
The inner wall of the cushion blocking 1 of cylindrical step outer rim and lower part coordinates, the cylindrical step outer rim of gland 2 and the cushion blocking 1 on top
Inner wall cooperation, 1 time outer rim cooperation of cushion blocking of counterbore side wall and top above mounting plate 4, the counterbore side below mounting plate 4
Outer rim coordinates on wall and the cushion blocking of lower part 1.
By taking the vibration damping of Payload Attach Fitting as an example, with the flange of screw connection plate 4 and the flange of Payload Attach Fitting, finally
The hole for passing through bushing center from top to bottom with screw is mounted in delivery support platform.
The course of work：
As shown in Figures 6 to 9, Fig. 6 is undeformed state, and Fig. 7 is when small deformation occurs, and apparent deformation, Fig. 8 occur for thin layer
When for moderate deformation occurs, apparent deformation occurs for intermediate gauge layer, and Fig. 9 is when moderate finite deformation occurs, and thick-layer occurs apparent
Deformation, the rigidity of 1 thin layer of cushion blocking is low, and the rigidity of thick-layer is high, and with the increase of amplitude, thin layer deformation reaches capacity, and squeezes thick
Layer, therefore cushion blocking 1 has the characteristics of " small rigidity when small amplitude, when large amplitude big rigidity ", when damper bears random vibration
When load, the vibration of the small amplitude of high frequency can be isolated in cushion blocking 1 by flexible deformation, simultaneously because its rigidity when amplitude increases
Increase, the effect for inhibiting resonance may be implemented.
