The outer diameter of each electromagnet is smaller than that of each magnetorheological elastomer, and the inner diameter of each electromagnet is not bigger than that of each magnetorheological elastomer.
Description
Technical field
The invention belongs to a kind of damper, be specifically related to the rock type MR damper of a kind of three-dimensional.
Background technique
It is a kind of complicated motion that three-dimensional is shaken; People normally adopt a plurality of dampers to make up to be its vibration damping; But this will make vibration damping structure become very complicated; So having designed again, people independently are used for the damper that three-dimensional is shaken; Like: one Chinese patent application number be: 2010105878118 " rock type MR damper ", although this MR damper can be used for the vibration damping occasion that three-dimensional is shaken, because magnetic flow liquid wherein is in case take place to leak or the sedimentation of magnetic flow liquid all can cause this MR damper performance decrease or inefficacy.
Summary of the invention
In order to overcome the defective of existing rock type MR damper, the present invention proposes the rock type MR damper of a kind of three-dimensional.
Technological scheme of the present invention is following: the rock type MR damper of a kind of three-dimensional, and it comprises: electromagnet and magnetic rheology elastic body; Electromagnet and magnetic rheology elastic body are ring; Three-dimensional rock type MR damper is by N+1 piece ring electromagnet and N piece annular magnetic rheology elastic body; The mode that changes mutually by an electromagnet and a magnetic rheology elastic body plane makes up and is fixed as one; The external diameter of electromagnet is not less than the external diameter of magnetic rheology elastic body, and the internal diameter of electromagnet is not more than the internal diameter of magnetic rheology elastic body.
Function of the present invention be achieved in that because of the rock type MR damper of three-dimensional be by N+1 piece ring electromagnet and N piece annular magnetic rheology elastic body; The mode that changes mutually by an electromagnet and a magnetic rheology elastic body plane makes up and is fixed as one; When an end of the rock type MR damper of three-dimensional fix and the other end when certain direction is crooked; Each the elastomeric one side of annular magnetic rheology that is between each ring electromagnet will be compressed, and the elastomeric another side of each annular magnetic rheology will be stretched; When electromagnet is not switched on; Just there is not the magnetic line of force through being in each the annular magnetic rheology elastic body between each ring electromagnet; Therefore; The elastomeric elasticity of each annular magnetic rheology between each ring electromagnet is less, and the other end of three-dimensional rock type MR damper suffered damping force when certain direction is crooked is less, and damping force suffered when just the other end of three-dimensional rock type MR damper shakes is less; After the electromagnet energising; Each electromagnet will generate an electromagnetic field; The magnetic line of force that this electromagnetic field produces will be through being in each the annular magnetic rheology elastic body between each ring electromagnet; Make the ferromagnetic particle in each annular magnetic rheology elastic body form chain or column aggregated structure and make its elasticity higher at magnetic direction; Therefore, the other end of three-dimensional rock type MR damper suffered damping force when certain direction is crooked is bigger, and damping force suffered when just the other end of three-dimensional rock type MR damper shakes is bigger; Get into the size of current in each ring electromagnet through adjustment; Can be through adjusting the electromagnetic field intensity that each ring electromagnet produces; Adjust the elastomeric elasticity size of each annular magnetic rheology; Thereby make three-dimensional rock type MR damper damping force obtain adjustment, compare, not only solved the leakage problem of magnetic flow liquid because of the rock type MR damper of three-dimensional with existing rock type MR damper; And can regulate separately through the ring electromagnet that is in its two ends because of the elastomeric elasticity of each annular magnetic rheology, the adjusting that makes three-dimensional rock type MR damper damping force is more flexibly and performance is better.

Embodiment
Specify structure of the present invention below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, this is a kind of concrete structure of the present invention, the rock type MR damper 1 of a kind of three-dimensional, and it comprises: electromagnet 4,6,8,10,12 and magnetic rheology elastic body 5,7,9,11; Electromagnet 4,6,8,10,12 and magnetic rheology elastic body 5,7,9,11 are ring; Three-dimensional rock type MR damper 1 is by 4,6,8,10,12 and 4 annular magnetic rheology elastic bodies 5,7,9,11 of 5 blocks of ring electromagnets; The mode that changes mutually by an electromagnet and a magnetic rheology elastic body plane makes up and is fixed as one; The external diameter of electromagnet 4,6,8,10,12 is not less than the external diameter of magnetic rheology elastic body 5,7,9,11; The internal diameter of electromagnet 4,6,8,10,12 is not more than the internal diameter of magnetic rheology elastic body 5,7,9,11; Control power supply 14 is connected with electromagnet 4,6,8,10,12 through going between; The plate washer 13 that permeability magnetic material constitutes is installed in the bottom of the rock type MR damper 1 of three-dimensional, plate washer 3 and pillar 2 that permeability magnetic material constitutes are installed at the top of the rock type MR damper 1 of three-dimensional.
Now combination figure Fig. 1, Fig. 2 and Fig. 3 further describe the rock type MR damper of three-dimensional of the present invention: when the 13 fixing backs, bottom of the rock type MR damper 1 of three-dimensional and during pillar 2 bending to the right of the other end; The right that is in each ring electromagnet 4,6,8,10, each the annular magnetic rheology elastic body 5,7,9,11 between 12 will be compressed, and the left side of each annular magnetic rheology elastic body 5,7,9,11 will be stretched (seeing Fig. 2 for details); When controlling power supply 14 not to electromagnet 4,6,8,10,12 output currents; Electromagnet 4,6,8,10,12 does not generate an electromagnetic field; Just there is not the magnetic line of force through being in ring electromagnet 4,6,8,10, annular magnetic rheology elastic body 5,7,9,11 between 12 yet; Therefore; The elasticity of ring electromagnet 4,6,8,10, the annular magnetic rheology elastic body between 12 5,7,9,11 is less, the pillar 2 of the other end of three-dimensional rock type MR damper 1 when spring is bent to the right suffered damping force less, suffered damping force less (seeing Fig. 2 for details) when the pillar 2 of the other end of just three-dimensional rock type MR damper 1 shakes;
When controlling power supply 14 behind electromagnet 4,6,8,10,12 output currents; Electromagnet 4,6,8,10,12 will generate an electromagnetic field; The magnetic line of force that this electromagnetic field produces will be through being in ring electromagnet 4,6,8,10, annular magnetic rheology elastic body 5,7,9,11 between 12; Make the ferromagnetic particle in the annular magnetic rheology elastic body 5,7,9,11 form chain or column aggregated structure and make its elasticity higher (seeing Fig. 3 for details) at magnetic direction; Therefore; The pillar 2 of three-dimensional rock type MR damper 1 the other end when spring is bent to the right suffered damping force bigger, damping force suffered when the pillar 2 of just three-dimensional rock type MR damper 1 the other end shakes is bigger; Through the size of current in the adjustment control power supply 14 entering ring electromagnets 4,6,8,10,12; Can adjust the electromagnetic field intensity that ring electromagnet 4,6,8,10,12 produces; Make the elasticity that is in ring electromagnet 4,6,8,10, the annular magnetic rheology elastic body between 12 5,7,9,11 obtain adjustment, thereby adjust the damping force size of three-dimensional rock type MR damper 1.
When the situation of pillar 2 when arbitrary direction is crooked of rock type MR damper 1 the other end of three-dimensional is similar with it, repeat no more here.
