Abstract
The invention discloses a magneto-rheological elastomer rigidity-adjustable helical spring, which comprises a helical spring and an annular external electromagnet or a cylindrical internal electromagnet, wherein the spring wire of the helical spring consists of a rectangular sectional magneto-rheological elastomer; and the outer diameter of the helical spring is less than the inner diameter of the annular external electromagnet, a gap is reserved between the helical spring and the annular external electromagnet, and the helical spring is arranged in the annular external electromagnet, or the inner diameter of the helical spring is greater than the outer diameter of the cylindrical internal electromagnet, a gap is reserved between the helical spring and the cylindrical internal electromagnet, and the cylindrical internal electromagnet is arranged in the helical spring. The rigidity of the magneto-rheological elastomer rigidity-adjustable helical spring can be adjusted only by adjusting current which is input into the annular external electromagnet or the cylindrical internal electromagnet, so that the rigidity of the magneto-rheological elastomer rigidity-adjustable helical spring can be adjusted at any time.
Description
Technical field
The invention belongs to a kind of helical spring, be specifically related to a kind of magnetic rheology elastic body adjustable rigidity helical spring.
Background technique
Common helical spring can be divided into by rigidity decides stiffness helix spring and variable stiffness coil spring two classes, this helical spring rigidity of two types all is predetermined when design, therefore, as long as after no matter deciding stiffness helix spring or variable stiffness coil spring and completing, their characteristic curve is exactly changeless, and rigidity or the characteristic curve of common helical spring when work also can not change at any time.
Summary of the invention
In case the deficiency that characteristic curve can not change at any time when the characteristic curve after finishing at common helical spring coiling immobilized and works the present invention proposes a kind of novel helical spring, that is: a kind of magnetic rheology elastic body adjustable rigidity helical spring.
Technological scheme of the present invention is as follows:
A kind of magnetic rheology elastic body adjustable rigidity helical spring, it comprises helical spring and ring-shaped external electromagnet or column in-built electrical magnet, wherein, helical spring spring silk is made of the magnetic rheology elastic body of rectangular cross-section, helical spring external diameter is less than the internal diameter of ring-shaped external electromagnet and leave the gap, helical spring be placed in the ring-shaped external electromagnet or helical spring internal diameter greater than the external diameter of column in-built electrical magnet and leave the gap, column in-built electrical magnet is placed in the helical spring.
Function of the present invention is achieved in that
Magnetic rheology elastic body is a kind of functional material that is made of high molecular polymer (as rubber etc.) and ferromagnetic particle, magnetic rheology elastic body has different rigidity under different externally-applied magnetic field effects, therefore, when the electric current in being input to ring-shaped external electromagnet or column in-built electrical magnet is zero, making by the helical spring magnetic intensity of magnetic rheology elastic body adjustable rigidity is zero, at this moment, the helical spring rigidity of magnetic rheology elastic body adjustable rigidity is minimum; When electric current is big in being input to ring-shaped external electromagnet or column in-built electrical magnet, make by the helical spring magnetic intensity of magnetic rheology elastic body adjustable rigidity higherly, make the helical spring rigidity of magnetic rheology elastic body adjustable rigidity higher; Therefore, be input to size of current in ring-shaped external electromagnet or the column in-built electrical magnet, can adjust the helical spring rigidity size of magnetic rheology elastic body adjustable rigidity, make the helical spring rigidity of magnetic rheology elastic body adjustable rigidity obtain at any time adjusting by adjustment.Because the helical spring rigidity of magnetic rheology elastic body adjustable rigidity can change when work as required at any time, therefore, compare the helical spring Applicable scope of magnetic rheology elastic body adjustable rigidity with common helical spring more extensive.

Embodiment
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
Referring to Fig. 1, Fig. 2, Fig. 3, this is a kind of concrete structure of the present invention, magnetic rheology elastic body adjustable rigidity helical spring comprises helical spring 1 and ring-shaped external electromagnet 2, the spring silk of helical spring 1 is made of the magnetic rheology elastic body 4 of rectangular cross-section, the external diameter of helical spring 1 is less than the internal diameter of ring-shaped external electromagnet and leave gap 3, helical spring 1 is placed in the ring-shaped external electromagnet 2, and ring-shaped external electromagnet 2 is connected with control power supply 5 by lead-in wire 6.
When control power supply 56 is input to electric current in the ring-shaped external electromagnet 2 when being zero by going between, the magnetic intensity that ring-shaped external electromagnet 2 is produced is zero, make the helical spring 1 that places ring-shaped external electromagnet 2 not have the magnetic line of force to pass through, make the rigidity of magnetic rheology elastic body 4 of rectangular cross-section minimum, at this moment, the helical spring rigidity of magnetic rheology elastic body adjustable rigidity is minimum; When control power supply 56 is input to electric current in the ring-shaped external electromagnet 2 when big by going between, the magnetic intensity that ring-shaped external electromagnet 2 is produced is higher, make the helical spring 1 that places ring-shaped external electromagnet 2 have the stronger magnetic line of force to pass through, make the rigidity of magnetic rheology elastic body 4 of rectangular cross-section higher, make the helical spring rigidity of magnetic rheology elastic body adjustable rigidity higher; Therefore, no matter magnetic rheology elastic body adjustable rigidity helical spring is to be in compression or to return to form, as long as be input to size of current in the ring-shaped external electromagnet 2 by adjustment, can adjust the helical spring rigidity size of magnetic rheology elastic body adjustable rigidity, make the helical spring rigidity of magnetic rheology elastic body adjustable rigidity obtain at any time adjusting.
