Abstract
The invention discloses a composite spiral spring. The spring wires are of the equal pitch; each spring wire is of a two-layer structure; the outer layer is a metal layer; and the inner layer is shearing thickening glue. By means of the spiral spring composited with the shearing thickening glue, static loads express the linear characteristic, and dynamic loads have the non-linear rigidity and damping characteristics because of the unique mechanical performance of the shearing thickening glue. The defects of existing springs are well overcome.
Description
Technical field
The invention belongs to mechanical driving device, more particularly to non-linear spring device.
Background technology
Spring has many performance requirements as a conventional mechanical organ in damper application.Most of at present
Although helical spring has application in practice, its main its geometry of profit and achieve the goal, pitches, variable cross-section make
Obtain spring geometry uneven, cause spring service life low, and dead load does not have linear characteristic, and spiral bullet at present
Spring damping capacity is poor.
Content of the invention
For the deficiencies in the prior art are solved, a kind of composite helical spring is provided, this composite helical spring simple structure is closed
Reason, easy for installation, its linear characteristic can be kept in dead load, and the excellent mechanical performance of shear thickening glue can be utilized, dynamic
Being capable of spontaneous regulation its damping, stiffness characteristics under load excitation.
For achieving the above object, the present invention is employed the following technical solutions：
Composite helical spring, spring wire pitch is equal, and it is metal level that spring wire is double-layer structure, outer layer, and internal layer is shear thickening
Glue.
This helical spring for being compounded with shear thickening glue, dead load shows linear characteristic, and dynamic load is due to shear thickening
Its unique mechanical properties of glue have non-linear rigidity, damping characteristic.The deficiency of existing spring is overcome well.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 composite helical spring overall structure diagram.
Fig. 2 dead load linear rigidity curve chart.
Fig. 3 dynamic load non-linear rigidity curve chart.
Fig. 4 damping characteristic curve figure.
Reference is：1 composite helical spring body, 2 outer layer metal layers, 3 shear thickening glue internal layers.
Specific embodiment
Present invention is achieved through the following technical solutions：
Composite helical spring, spring wire pitch is equal, and spring wire is made up of two-layer, and it is shear thickening that outer layer is metal level, internal layer
Glue.
Outer layer equal pitch metal helical structure, as the spiral-shaped supporting construction of shear thickening glue, only has line during stress
Property characteristic.
Shear thickening glue（Dimethicone, pyroboric acid and benzoyl peroxide）, when the increase with shear rate, just
Solid can be become as typically hard, in shear rate very little, it is soft as colloid, be mainly used in protection field,
Vibration reduction and cushioning field.
This programme, by shear thickening glue by being heated to uniform temperature so as to good flow performance.Again heating is cut
Cut thickening glue to pour in outer layer metal helical spring structure, be cooled to room temperature and form complex spring structure.
Before heating and after heating, shear thickening glue mechanical property is basically unchanged.
Complex spring also has excellent nonlinear characteristic compared with original hollow screw structure.
The present invention, it is only necessary to exert a force at composite helical spring two ends, you can represent its unique mechanical of composite helical spring
Can, stressed condition changes and responds to external world, shows non-linear rigidity, damping characteristic.
In Fig. 2 dead load linear rigidity curve chart, abscissa is spring deflection, and vertical coordinate is spring force.
In Fig. 3 dynamic load non-linear rigidity curve chart, abscissa is spring deflection, vertical coordinate is spring force.
Fig. 4 damping characteristic curve in figure abscissa is weighed for position, and vertical coordinate is damping force.
