Description

A kind of MR vibration damper for helicopter high-definition camera installation and debugging
Technical field
The present invention relates to fluid damper technical field.It is used to helicopter high-definition camera more particularly, to one kind pacify The MR vibration damper of adjustment examination.
Background technology
Aviation machine construction environment is severe, and job status is complicated, and the requirement to pass heavy parts is very high.High-definition camera subtracts Device is shaken as one of important Parts in aviation machine, it is desirable to which it is conveniently applicable, structure is light, reliability is high.High-definition camera uses During, helicopter vibration is big, has very big interference to the shooting effect of camera, and the image of camera shooting is smudgy, Therefore the mounting shock absorber between camera and helicopter is needed, reduces influence of the helicopter vibration to camera.Market at present On damper typically have air bump, rubber absorbers and steel rope damper etc..Its elasticity after these dampers dispatch from the factory Determined that with damping, it is impossible to change is adjusted again, and height is can guarantee that, it is necessary to install in the installation process of high-definition camera Clear camera photographs the damper with suitable elasticity and damping of clear picture effect, and in order to install suitable high-definition camera Damper needed for head work, then it is it needs to be determined that required during high-definition camera shooting clear picture under helicopter flight state The elasticity and damping parameter of damper, then according to the parameter of determination, suitable damper is installed, therefore in order to reduce test work That makees is convenient and swift, it is necessary to design the damper of low-cost and high-performance convenient use.
The content of the invention
It is an object of the invention to provide a kind of MR vibration damper for helicopter high-definition camera installation and debugging, side Just the elasticity between camera and helicopter and damping are adjusted.
To reach above-mentioned purpose, the present invention uses following technical proposals:
A kind of MR vibration damper for helicopter high-definition camera installation and debugging, the MR vibration damper include: Pedestal, coil and magnetic flow liquid;
The pedestal includes the first connecting portion being connected with camera and the second connecting portion affixed with helicopter;Described One connecting portion includes accommodating the first receiving portion of coil and accommodates the second receiving portion of magnetic flow liquid, and first receiving portion is surround In the periphery of second receiving portion.
Further, the MR vibration damper also includes cell body;The first connecting portion includes a groove, the groove Side wall be provided with the first receiving portion for accommodating coil, the inside grooves accommodate cell body, and the side wall of the cell body is provided with Accommodate the second receiving portion of magnetic flow liquid.
Further, first receiving portion is the first annular groove, and second receiving portion is the second annular groove.
Further, the MR vibration damper also includes motion bar, and the inside of cell body is stretched into one end of the motion bar And it is connected with bottom land.
Further, the motion bar is provided with screwed hole, and the material of the motion bar is aluminium.
Further, the second connecting portion of the pedestal is threaded rod, and the material of the pedestal is aluminium.
Further, the material of the cell body is vulcanization rubber.
Beneficial effects of the present invention are as follows:
(1) structural reliability is high, and vulcanization rubber is provided between pedestal and motion bar, and coil is arranged in base seat groove, structure It is compact.Pedestal and motion bar are all that aluminum casting forms, therefore construction weight is small.
(2) elasticity and damping are adjustable, and coil and magnetic flow liquid are provided with damper, pass through and change inflow coil current Size can change elasticity and the damping of damper.
Brief description of the drawings
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the overall appearance schematic diagram of MR vibration damper of the present invention;
Fig. 2 is MR vibration damper structural representation of the present invention.
In figure:1- pedestals;2- coils;3- cell bodies;4- motion bars;5- base thread bars;6- magnetic flow liquids;7- screwed holes.
Embodiment
In order to illustrate more clearly of the present invention, the present invention is done further with reference to preferred embodiments and drawings It is bright.
As illustrated in fig. 1 and 2, MR vibration damper includes pedestal 1, coil 2, cell body 3, motion bar 4, threaded rod 5, magnetorheological Liquid 6 and screwed hole 7;Pedestal 1 includes the first connecting portion being connected with camera and the second connecting portion affixed with helicopter;First Connecting portion includes accommodating the first receiving portion of coil 2 and accommodates the second receiving portion of magnetic flow liquid 6, and the first receiving portion is looped around institute State the periphery of the second receiving portion;Specifically, first connecting portion includes groove, the side wall of groove, which is provided with, accommodates the first of coil 2 Receiving portion, inside grooves then accommodate cell body 3, and the side wall of cell body 3 is provided with the second receiving portion for accommodating magnetic flow liquid 6;
First receiving portion is the first annular groove, and the second receiving portion is the second annular groove;One end of motion bar 4 is stretched into cell body 3 simultaneously It is connected with the bottom land of cell body 3, the material of cell body 3 is vulcanization rubber, and motion bar 4 is provided with screwed hole 7, and camera passes through screwed hole 7 are connected with motion bar, and because motion bar 4 is connected with vulcanizing the cell body 3 of quality of rubber materials, thus between motion bar 4 and pedestal 1 Elasticity and damping are provided with, meanwhile, because being additionally provided with the first annular groove of installation coil 2 on pedestal 1, the side wall of cell body 3 is provided with The second annular groove groove of magnetic flow liquid 6 is accommodated, the first annular groove is looped around the periphery of the second annular groove, when coil 2 is powered, it is possible to Electromagnetic field is formed, the state of magnetic flow liquid 6 is changed, so as to produce damping, therefore shaking for pedestal is transferred to by helicopter Dynamic loading can reduce, and so as to play a part of damping to camera, bottom of the pedestal 1 outside groove is provided with threaded rod 5, pedestal 1 is affixed by threaded rod 5 and helicopter.
Installation and debugging of the present invention are simple, and quality is small, are suitable for use in the damping of helicopter high-definition camera.When in use, open Dynamic helicopter engine, allow the vibration of helicopter to be in normal operating conditions, open the image of high-definition camera observation shooting, to Different size of electric current, the image of observation camera shooting, until image stabilization is clear are passed through in coil;Record is now in coil The size of electric current, measure the now elasticity of damper of the present invention and damping using relevant device, you can it is determined that needing to install Damper performance parameter, reached high-definition camera damping debugging purpose.
