Description
Technical field
The utility model belongs to airframe experimental design field, and in particular to a kind of box section towards different loads level
To connected components.
Background technique
Currently, composite material application on civil aircraft need to pass through comprehensive building block system verification experimental verification, including it is typical box section grade, big
Type section grade test etc., such testpieces often design a bogusware box section, the equivalent application of external load on the outside of examination box section
In the bogusware box section, to guarantee the authenticity of examination box section borne load.Bogusware box section structure is generally divided into two kinds: first is that
Examination section composite material parts are directly extended as bogusware box section；Another kind is one can section of manufacture, even using machinery
Form is connect to dock with examination section.The former reduces assembly difficulty, but multiple material die cost, material cost are higher, and bogusware
Box section must be designed sufficiently strong, and composite Materials Design manufacture difficulty is larger；Cost is relatively low by the latter, but assembles complicated, test
Part integrally increases weight larger.By taking the test of the typical box section of composite wing as an example, test objective is verifying wing root structure
Bearing capacity, bogusware box section bear equivalent load it is higher, be typically designed as can section, docked with multiple material box section.
For existing box section testpieces docking concept as shown in Figure of description 1, Fig. 2 and Fig. 3, testpieces examines box section and bogusware
Box section is connected using interior outside jointing strip plate, tandem docking side plate, carries out whole docking to the rib position close to wing tip in exhibition.
Siding is mechanically connected using interior outside jointing strip plate, wherein interior docking band plate design overlap joint slot is last to connect examination box segment length purlin
End；Front and back spar carries out simple shear connection using opposed side panel；Rib and siding are mechanically connected at docking.Examine box section siding, the wing
Liang Jun is truncated at rib section and connect with bogusware box section；As shown in figure 3, testpieces two sides are clamped, apply among box section and carry
Lotus.For bogusware box section without applying additional equivalent load, docking area load level is relatively low.And for similar examination wing root area
Load-transfer mechanism on the outside of box section to bogusware box section, docking area need to be born load-carrying water by the wing-box cantilever design testpieces of structure
It puts down relatively high.Existing docking design is unsatisfactory for big load test requirements document.It is specific as follows:
1) box section docking area siding, spar dock at same rib section, and stiffness variation is excessive, and stress is concentrated tight at section
Weight；
2) spar docking uses simple shear form, and in the case where bearing larger shear loads, the type of attachment is on the weak side；
3) siding uses band card slot type monoblock type to dock, and assembles location difficulty, under big load effect, compatibility of deformation is difficult.

Further, it is respectively provided on sectional type angle box, band plate, cornual plate and lateral angle box affixed convenient for screw accordingly
Through-hole.
Self-box section is connected to connected components and when bogusware box section using described in the utility model, by the wall of ontology and bogusware
Plate, the docking of spar partial cross-section, spar docking use double shear form, and siding docking inside is connected using cornual plate.
Further, the docking stringer edge strip and web are arranged fastener, reduce Assembly part quantity, reduce fastening
Part arrangement difficulty.
Further, the double shear structure refers to three part connections, and there are two contact surfaces, is two for bolt
Shear surface；The described of the utility model tests connected components for the horizontal box section of big load, in box section docking location, loaded feelings
Condition is complicated, load is larger, and it is more stable when testing, safe to make box section using double shear structure, and reduces the wind of Failure Analysis of Composite Materials
Danger.
Further, it is known in the art that having covering, similarly, the bogusware box section on the outside of the stringer of the self-box section
Stringer on the outside of with one layer of covering.
Further, the material of the covering is composite material or aluminium alloy.
The utility model at least has following advantageous effects:
(1) the utility model it is a kind of towards different loads it is horizontal to connected components, when docking, can be made using double shear structure
Box section is more stable when testing, safe, and reduces the risk of Failure Analysis of Composite Materials.
(2) a kind of box section towards different loads level of the utility model assembles connected components simple, convenient for operation.
(3) box section docking area siding, the wing of a kind of box section towards different loads level of the utility model to connected components
Beam docks not at same rib section, and stiffness variation is small, and stress disperses at section.
