Show system.
Background technology
Visual display system is the important component part of flight simulator, and driver can be made to produce sensation on the spot in person
Real-time vision simulated environment, realizes that driver directly carries out information exchange with the outer visual environment simulated of passenger cabin.Visual display
The product quality of system is the important guarantee of flight simulator fidelity of simulation, and is conducive to improving simulated test and training matter
Amount.
In flight simulator visual display, mainly there is the virtual image to show with real image and show two ways.
The virtual image shows and refers to thing is positioned at one times of focal length of optical element, in the distance into the upright amplification virtual image, similar to
Look in the mirror (without focal power, into etc. the big virtual image).Virtual image display mode has the features such as depth of field sense is strong, imaging fidelity is high, but,
Virtual image visual display system is caused the angle of visual field less as vertical field of view limits by system architecture, and system architecture complexity,
Manufacturing cost is high.
Real image visual display system point post curtain real image visual display system, two kinds of ball curtain real image visual display system again.Ball
Curtain real image visual display system is more higher to the feeling of immersion that driver brings than post curtain real image visual display system.Also, ball curtain reality
As visual display system architecture is simple, (vertical maximum up to 200 °, visual field is maximum reachable 60 ° thereon greatly for low cost, vertical field of view
Lower visual field is maximum up to 140 °).
In traditional ball curtain real image visual display system, its ball curtain is made using composite and is processed, and projector is straight
Connect and be fixed on ball curtain.In flight simulator motion process, system is hit the effect of load, and ball curtain stress itself can simultaneously be produced
Raw moderate finite deformation amount, and then cause display picture to deform and shake, affect training quality.
The content of the invention
The invention provides a kind of high intensity, high rigidity, the high natural frequency of vibration, low weight, centre of gravity, the ball curtain reality of low inertia
As display system, the display system disclosure satisfy that use of the full dynamic formula flight simulator to overall structure " three high " and " three is low " will
Ask.
The present invention adopts the following technical scheme that to realize.
A kind of big visual field ball curtain real image display system of high intensity, mainly includes steel structure support part and ball curtain；The steel knot
Structure support member includes motion upper mounting plate, doorframe, some warp-wise support units and some broadwise support units；In steel structure support part
Supporting construction of the portion for adaptive to spherical screen shape；Each part of steel structure support part is designed to several subelements,
It is bolted between each subelement.
Doorframe on steel structure support part is corresponding with the gateway of motion upper mounting plate.
The Pressurized-heated in the hyperboloid large area high accuracy steel construction mould is solid using preimpregnation glass fabric of epoxy resin for ball curtain
Turn to shell ball curtain cell cube.
Strengthened with glass fabric of epoxy resin in the seam crossing of steel structure support part and ball curtain inner surface.
Beneficial effect
The big visual field ball curtain real image display system of high intensity of the present invention, each part of steel structure support part are all provided with
Several subelements are counted into, is bolted between each subelement, its intensity, rigidity and the natural frequency of vibration are high, weight, center of gravity and used
Amount is low, meets full dynamic formula flight simulator to overall structure " three high " and the use requirement of " three is low ".The system also has and regards simultaneously
Rink corner is big, simple structure, manufacturing cycle are short, the features such as low cost, can meet the use in the fields such as flight simulation, scientific research, amusement
Require.

Specific embodiment
In order to better illustrate objects and advantages of the present invention, with reference to the accompanying drawings and examples present invention is made into
One step explanation.
As Figure 1-3, the big visual field ball curtain real image display system of high intensity of the invention, mainly includes steel structure support part
1 and ball curtain 6.
Referring to accompanying drawing 1, if the steel structure support part 1 include motion upper mounting plate 4, doorframe 5, some warp-wise support units and
Dry broadwise support unit.Skeleton of the steel structure support part 1 as display system, withstand shocks load.On steel structure support part 1
Doorframe 5 is corresponding with the gateway of motion upper mounting plate 4.
Each part of steel structure support part 1 is designed to several subelements, passes through bolt between each subelement
The overall steel structure support part 1 of connection composition.Each subelement can adopt Q345 steel, using plasma cut, welding plus
The variable cross-section rib I-steel of raw material such as sheet metal composition is processed into design form by work means.Used in welding process
Special high-accuracy hyperboloid weld mold, it is ensured that the geometric accuracy of the variable cross-section rib I-steel of sheet metal composition.
The warp-wise of steel structure support part 1, broadwise are supported and are fixed using convergence piece between subelement.
To mitigate the weight of skeleton, on the premise of support strength is not affected, the warp-wise in steel structure support part 1 may be selected
On beam parts steel plate, hole is set.
The bottom of motion upper mounting plate 4 is provided with for fixed fixed structure and/or for mobile walking mechanism.
The Pressurized-heated in the hyperboloid large area high accuracy steel construction mould is solid using preimpregnation glass fabric of epoxy resin for ball curtain 6
Turn to shell ball curtain cell cube.After 1 overall package of steel structure support part, the internal supporting construction for 6 shell shape of adaptive to spherical screen.
