Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to air wing plate for aerodynamic braking of the present invention.
See accompanying drawing 1, the dual-side embowment backward of wind wing main body panel 1; rocking arm 2 is fixedly connected on the back side of wind wing main body panel 1 by the jointing be preset in wind wing main body panel 1; rocking arm 2 is two; be symmetrical arranged in wind wing main body panel 1; rocking arm 2 is provided with installation hole slot, for being fixed on mount pad by the wind wing plate of turning motion and being connected to driver train.In the central authorities of the lower rear of wind wing main body panel 1, be provided with middle base 4, middle base 4 is also fixedly connected with by the jointing be preset in wind wing main body panel 1, and middle base 4 is provided with mounting hole, for wind wing plate being fixed on mount pad together with rocking arm 2.The selection of rocking arm 2 and middle base 4, from corrosion prevention and tired angle, is selected 7075 high strength aluminum alloys, is compared steel material, can effectively reduce structure dimension and weight.Rocking arm 2 and middle base 4 adopt the attaching parts being embedded in wind wing main surface 1 to be in advance connected, according to the modular design principle that high-performance composite materials are connected with metal piece, take into account and consider product forming technique feature, attaching parts and wind wing main body panel 1 adopt glueds joint connection mode.Below the reverse side of wind wing main body panel 1, two secure latch 3 are installed between two rocking arms 2 and middle base 4, the installation of secure latch 3 is mainly considered occurring the fault of extreme, when relying on hydraulic efficiency pressure system and S. A. thereof all wind wing plate cannot be fixed, the U-bolt be fixed on roof is now relied on to fasten secure latch 3, in the situation of breaking down, guarantee that wind wing plate can not depart from roof, thus avoid causing damage to roof miscellaneous equipment.In the central authorities of the back side top of wind wing main body panel 1, magnetic key operated lock magnet 5 is installed, train is in normal driving process, wind wing plate should be in closure state all the time, now magnetic key operated lock magnet 5 and mount pad produce suction, magnetic key operated lock magnet 5 is tightly held, under preventing hydraulic efficiency pressure system from occurring unusual condition, causes the misoperation of wind wing plate.Install proximity switch 6 in the bilateral symmetry of the magnetic key operated lock magnet 5 of the back side of wind wing main body panel 1, proximity switch 6 Main Function judges whether wind wing plate is in closure state, and the location information of wing plate of keeping watch delivers to control system.
See accompanying drawing 2, consider the impact of the environment such as the aerodynamic loading residing for wind wing plate in the course of the work, humiture, impact and corrosion, and the factor such as material property, cost and supply channel, wind wing main body panel 1 adopts that multilayer materials structure is gluing to be formed.Be made up of carbon fibre reinforcement layer 11, fiber glass reinforcement layer 12, foam core material layer 13, fiber glass reinforcement layer 14 and carbon fibre reinforcement layer 15, wherein carbon fibre reinforcement selects T700/9368 unidirectional prepreg tape, fiber glass reinforcement selects SW280/9368 unidirectional prepreg tape, above-mentioned prepreg tape excellent material performance, material permissible is 4000 μ ε, have good shop characteristic and heat stability, reliability is higher simultaneously.Foam core material selection polyvinyl chloride foam (PVC foam) material, foam density is 80Kg/m
3, there is good Heat forming stability.Gluing shaping by adhesive film material between each material layer, adhesive film material selects J47-A and J47-B bi-component glued membrane, and this material has good heat stability and anti-fatigue performance.In order to increase considerably the counter-bending of wind wing plate and torsional rigidity, unreasonable distortion can be effectively stoped when change appears in the motion of wind wing plate and aerodynamic loading, reduce the impact of uncertain factor (as flutter etc.) on wind wing braking effect and structural stability, guarantee the integrally-built reliability of the wind wing simultaneously, arrange in foam core material in length and breadth muscle 7(see accompanying drawing 3), muscle 7 is formed by horizontal bar 71 and vertical muscle 72 cross arrangement in length and breadth.Muscle selects carbon fibre reinforcement T700/9368 unidirectional prepreg tape in length and breadth, makes full use of the feature of carbon fibre reinforcement high-modulus.Under the aerodynamic loading effect of using above structure that train is caused in high-speed cruising, wind wing plate integral structure not unstability, the jointing established in wind wing main body panel 1, in length and breadth rib 7 and wind wing main body panel 1 is in elastic range.One side adopts carbon fiber layer, glass layer laying can improve the impedance of low speed exotic concussion damage, on the other hand, uses 80Kg/m
3pVC foam sandwich construction can prevent high speed exotic from impacting (as birdstrike).
See accompanying drawing 4,5, consider that wind wing plate and the metal piece junction such as rocking arm 2, middle base 4 and wind wing plate edge stress are comparatively concentrated, to bottom the region 21 of windward side upper side and wind wing plate, the region 22 of the joint of wind wing main body panel 1 carried out benefit rigidity and mended Intensity Design, to ensure the distortion of wind wing plate each several part evenly.The method of mending rigidity and reinforcement degree is increased region 21 and the layer of carbon fiber material 11 at region 22 place and the thickness of layer of carbon fiber material 15.The thickness of each layer is as shown in the table:
| Layer | Mend firm and reinforcement district thickness (mm) | Other area thickness (mm) |
| Layer of carbon fiber material 11 | 1.3 | 0.65 |
| Glass fiber layer 12 | 1.2 | 1.2 |
| Foam core material layer 13 | 20 | 20 |
| Glass fiber layer 14 | 1.2 | 1.2 |
| Layer of carbon fiber material 15 | 1.3 | 0.65 |
The layer of carbon fiber material 11 of both sides and the thickness of layer of carbon fiber material 15 increase, and add the rigidity of mending stiffness region 21, add the intensity of mending intensity region 22.
Owing to there is potential corrosion between carbon fiber composite material and the metallic material being arranged on the jointing in wind wing main body panel 1, therefore, adopt the method for wrapping up glass fabric at metal joint and composite material contact site by carbon fiber composite material interface and metal interface isolated, guarantee metallic material is not by potential corrosion.In the method for the surface spraying anti-static coatings of wind wing main body panel 1, effectively prevent the surface of wind wing main body panel 1 and windage from producing static hazard.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
