Description

The magnetic rheology elastic body vibration isolator
Technical field
The utility model belongs to the mechanical ﹠ electrical technology field, is specifically related to a kind of vibration isolator of magnetic rheology elastic body material.
Background technique
At present, structural vibrations isolate with control in, isolation mounting commonly used mainly contains two kinds of passive type vibration isolator and active vibration isolators.The passive type vibration isolator does not have regulating power fully owing to adopt General Purpose Rubber or metal spring as damping member, and certain narrow limitation is arranged.And the general structure of active vibration isolator is complicated, need consume a large amount of energy, thereby has limited its application in engineering reality.In order to overcome the narrow limitation of the single passive or active vibration isolation method of tradition, in recent years, existing people utilizes the magnetic rheology elastic body material to come the active-passive integrated vibration of implementation structure to isolate and control, but the structural type that adopts is generally shearing force way, it is the effect that the magnetic rheology elastic body material is subjected to shearing force, there is the little shortcoming of bearing capacity in this structural type, should not be used for big load micro breadth oscillation occasion.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective that exists in the prior art, provides a kind of active-passive integrated vibration that can adapt to heavily loaded micro breadth oscillation structure to isolate and the extruding type magnetic rheology elastic body vibration isolator of controlling.
The utility model is to realize above-mentioned purpose by the following technical solutions: the feature of this magnetic rheology elastic body vibration isolator is: its magnetic rheology elastic body is fixed on columniform going up between magnet case and the following magnet case, be embedded with coil winding and lower coil winding respectively in the groove on the external peripheral surface of last magnet case and following magnet case, the top of last magnet case is connected with connecting rod; Last magnet case, magnetic rheology elastic body, the bottom of magnet case and connecting rod all places in the magnetic urceolus down, is provided with cover plate every the top of magnetic urceolus, stretches out the through hole of the top of connecting rod from cover plate and is connected with controlled device; Be fixed with sensor on the connecting rod, sensor is connected with power amplifier by control unit, and power amplifier then links to each other with the lower coil winding with last coil winding by elastic cable paper; All adopt the non-magnetizer material to make every magnetic urceolus, cover plate and connecting rod.
The utility model compared with prior art has the following advantages:
1, owing to adopted magnetic rheology elastic body as damping material, and closed loop control system, thereby have the active-passive integrated control function of self adaption, can improve structural vibrations and isolate and the control effect.
2, magnetic rheology elastic body bears the extrusion load effect, has improved the bearing capacity of vibration isolator greatly.
3, constitute sealed cavity at magnetic rheology elastic body and the peripheral non-magnet material that adopts of upper and lower magnet case, make the magnetic line of force in the urceolus cavity, form closed loop, can improve the working efficiency of magnetic rheology elastic body.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1, fluted on the external peripheral surface of last magnet case 6 and following magnet case 3, groove is embedded with coil winding 5 and lower coil winding 1.Magnetic rheology elastic body 2 is fixed between magnet case 6 and the following magnet case 3, bears the extrusion load effect, and places in magnetic urceolus 4 with upper and lower magnet case; Be provided with cover plate 10 every the top of magnetic urceolus 4.The bottom of connecting rod 7 adopts the top of screw and last magnet case 6 to link together, and the top of connecting rod 7 is then stretched out the through hole from cover plate 10 and is connected with controlled device 8.The control system of being made up of the sensor 9, control unit module 12 and the power amplifier 11 that are fixed on the connecting rod links to each other with lower coil winding 1 with last coil winding 5 by cable.Upper and lower magnet case is a soft iron magnetic material, makes by non-magnet material every magnetic urceolus 4, cover plate 10 and 7 of connecting rods, makes the magnetic line of force form closed loop in the cavity of magnetic urceolus.Bottom every magnetic urceolus 4 is provided with outer lug boss, and through hole is arranged on the outer lug boss, can whole vibration isolator be installed on the desired position with screw by this through hole.
After last coil winding 5 and 1 energising of lower coil winding, produce magnetic field at last magnet case 6 and 3 of following magnet cases, the action of a magnetic field is on magnetic rheology elastic body 2.Magnetic rheology elastic body 2 belongs to a kind of of magnetorheological materials, is the intelligent solid material that a kind of rigidity and damping are subjected to externally-applied magnetic field control, and its main constituent comprises as the rubber-like damping material of body material and dispersion magnetic powder particle wherein.
The working principle of vibration isolator shown in Figure 1 is: the oscillating signal of controlled device sends to control unit module 12 by the sensor 9 that is fixed on the connecting rod, control unit module 12 requires the size of current in the coil winding 5 and lower coil winding 1 in the timely adjustment according to the vibration characteristics of controlled device 8 and vibration isolation, magnetic intensity in the control between magnet case 6 and the following magnet case 3, and then the rigidity and the damping of change magnetic rheology elastic body 2, like this with regard to the power consumption of may command magnetic rheology elastic body 2, thereby reach required active-passive integrated vibration isolating effect.
Because magnetic rheology elastic body 2 places between magnet case 6 and the following magnet case 3, bears the extrusion load effect, has improved the bearing capacity of vibration isolator greatly, and simple in structure.
