Description
Technical field
The utility model relates to a kind of horizontal great cantilever gas cylinder supporting construction, belongs to carrier rocket air feed field.
Background technology
Gas cylinder is one of requisite critical component of Large Launch Vehicle, is mainly used in into tank supercharging and for power system air feed.Gas cylinder is fixed on rocket body inside by gas cylinder supporting construction, need meet following several basic demands: the first during gas cylinder support structure designs, has good static strength to carry the deadweight after inflating gas cylinder and overload; Second: there is good rigidity and be out of shape in load bearing process to avoid supporting construction; 3rd: there is good self stability and connective stability, the fatigue resistance requirement of gas cylinder to supporting construction can be met, excessive to avoid responding in the middle of vibration processes.
In the conventional model rocket of China, the installation form of gas cylinder on rocket body is generally longitudinal, and gas cylinder supporting construction generally adopts knockdown panel beating support, in order to improve support rigidity, and general employing cartridge design form.But longitudinal space has in limited time, need adopt the placement scheme that gas cylinder is horizontal.
Utility model content
Technical problem to be solved in the utility model is: for overcoming the deficiencies in the prior art, provides a kind of horizontal great cantilever gas cylinder supporting construction of reliable, lightweight.
Technical solution of the present utility model is:
A kind of horizontal great cantilever gas cylinder supporting construction, comprise joint face, attachment face, wherein joint face and attachment face are connected by transition face and jointly form a face, joint face is perpendicular to transition face, two attachment face inside are provided with stay bearing plate, and reinforced rib is perpendicular to stay bearing plate and joint face, and joint face is two planes of symmetry, attachment face is two planes of symmetry, all symmetrical relative to face, reinforced rib place; Attachment face one side is provided with connecting bore, and connecting bore and reinforced rib are located on the same line, and the another side of attachment face are provided with corresponding handle hole coaxial with connecting bore.
Joint face, transition face, attachment face, stay bearing plate and reinforced rib are that solid forging is shaping.
The aperture of handle hole is greater than the aperture of connecting bore.
The beneficial effects of the utility model:
The utility model has arm length, feature that integral rigidity is good for the gas cylinder supporting construction that conventional panel beating combines, gas cylinder supporting construction have employed box-like structure form, strengthen longitudinal resistance to bending, structure unstability under great cantilever effect is avoided to lose efficacy, increasing is widened with the joint face of housing, ensure connection reliability, improve lateral stiffness and the twisting resistance of structure simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that schematic diagram is used in installation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the joint face 1 of the utility model two symmetry is connected by transition face 3 with two symmetrical attachment faces 2, joint face 1 is perpendicular to transition face 3, and joint face 1 vertical and horizontal width is suitably increased according to the needs of coupling stiffness and widened, effectively to improve the longitudinal frequency after gas cylinder installation; Two attachment face 2 inside are provided with stay bearing plate 4, after the utility model is connected with extraneous housing, there is good integral rigidity, stay bearing plate 4 and joint face 1 are provided with reinforced rib 5; Above-mentioned plate is not intersecting vertical with vertical between plate, is only face vertical with the contact in face; Attachment face 2 one side is provided with connecting bore 6, gas cylinder structure is fastened on attachment face 2 by bolt and connecting bore 6, connecting bore 6 and reinforced rib 5 are located on the same line, namely reinforced rib 5 layout is on radial load path, ensure good power transmission efficiency, the another side of attachment face 2 is provided with corresponding handle hole 7 coaxial with connecting bore 6, undertaken tightening by handle hole 7 during fastening nut and the applying of moment, avoid occurring spanner insufficient space when there is assembling, cause and tighten and moment applying difficulty, handle hole 7 plays the effect of structure loss of weight simultaneously.
As shown in Figure 2, gas cylinder supporting construction 8 of the present utility model is generally placed in the middle boxes 10 of housing with rocket body structure, and gas cylinder 9 is connected by the attachment face 2 of the supporting structure of self with the gas cylinder supporting construction 8 on rocket body structure.In order to ensure the intensity that gas cylinder 9 is installed and stability, middle boxes 10 wants corresponding reinforcement, adapter plate 1 and middle boxes 10 is only needed to link together when gas cylinder supporting construction 8 is connected with rocket body middle boxes 10, preferentially select rivet, if select screw to connect, need to select shearing resistance screw to ream and connect, avoid because the structure partial frequency that coupling stiffness weakness causes reduces.
Prove the overall box-shaped design by the utility model structure self through finite element analysis, and be connected preferably with housing, meet the single carrying of group gas cylinder supporting construction 25Kg, axial acceleration 10g, the designing requirement of transverse acceleration 2g.
The unexposed technology of the utility model belongs to general knowledge as well known to those skilled in the art.
