Description

A kind of box section towards different loads level is to connected components, interconnection method and application
Technical field
The invention belongs to airframe experimental design fields, and in particular to a kind of box section docking towards different loads level Component, interconnection method and application.
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.
Summary of the invention
To solve the above problems, the present invention proposes a kind of box section towards different loads level to connected components, interconnection method And application;For the box section interconnection method when box section is docked, siding, the docking of spar partial cross-section, spar docking use double shear form, Siding docking inside uses piecemeal corner strip type connection scheme, and this method assembly is simple, and it is horizontal especially to can be adapted for different loads It is the box section test of big load level, reduces assembly difficulty and empirical risk.
The present invention is achieved by the following technical solutions:

Further, the docking stringer be self-box segment length purlin and bogusware box segment length purlin docking after obtain.
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.
A kind of box section interconnection method towards different loads level, the box section interconnection method are using described to connected components Self-box section and bogusware box section are connected, the siding of ontology and bogusware, spar partial cross-section are docked, spar docking uses double shear shape Formula, siding docking inside are connected using cornual plate.
Further, the box section interconnection method specifically comprises the following steps:
S1, self-box section siding dock in advance with bogusware box section siding;
S2, self-box section siding stringer of docking adjacent with bogusware box section siding docking area use internal sectional type angle box, And it is affixed to cooperate the band plate in outside to carry out, the band plate and sectional type angle box realize double shear structure;
S3, self-box section spar and bogusware box section spar dock at rib, and internal jointing and lateral angle box make the wing Web realizes double shear structure;It is connected inside spar flange using cornual plate, it is external to be shared with the band plate, it is same to realize double shear knot Structure.
Further, self-box section siding described in the step S2 and bogusware box section siding docking area use internal piecemeal The specific connection method of formula angle box is as follows:
After the self-box section siding and bogusware box section siding docking, at this point, the stringer of two box sections is also accordingly docked Docking stringer is formed, then is connected the inside of the adjacent long case bay of docking using sectional type angle box.
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 box section interconnection method of the invention is for the horizontal box section test 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.
Another object of the present invention is to provide a kind of box section interconnection methods towards different loads level to be applied to difference The box section test of load level especially big load level reduces assembly difficulty and empirical risk.
