Technical Field
The utility model belongs to the technical field of aircraft structural design, a compound material wing spar web trompil reinforcement is related to.
Background
In general, a through hole needs to be formed in a web of a spar in order to meet the design requirements of a system. For composite wings, the web openings destroy the structural integrity and continuity of force transfer, so opening reinforcements are required to be arranged to enhance the loading capacity of the web and improve the stability of the web.
The opening can not be reinforced by reinforcing structures such as a cover and the like, so that the opening part of the beam web is reinforced by the reinforcing part for opening the opening, and the design requirement of the spar is met. The common reinforcing mode of the composite beam web is that the local thickness of the periphery of the opening is increased, and longitudinal and transverse reinforcing ribs are arranged on the periphery of the opening. Therefore, the relative difficulty in the laying and forming process of the composite beam is increased, and the number of parts and the assembly relation are more.
SUMMERY OF THE UTILITY MODEL
The utility model provides a compound material wing spar web trompil reinforcement to improve the stability of web and the outer load of diffusion beam surface.
A web plate opening reinforcing piece of a composite machine wing beam is an integrally formed 'well' -shaped web plate 1, the center of the 'well' -shaped web plate is provided with a circular opening, and the circular opening is equal to the opening of a beam web plate in size;
a plurality of bolt holes are uniformly distributed in the transverse web plate, and the opening direction of the bolt holes is the same as the circular opening direction;
bolt holes around the round hole of the web plate in the shape of the Chinese character 'jing' are connected with the beam web plate through first flat-head high-locking bolts 4;
bolt holes at the upper end and the lower end of the 'well' -shaped web are simultaneously connected with the suspension support arm 2 and the beam web 6 through a second flat-head high locking bolt 7.
Furthermore, the upper end and the lower end of the well-shaped web plate are respectively provided with an integrally formed flanging;
the upper end flanging of the 'groined' shaped web plate is simultaneously connected with the upper edge strip of the beam and the upper wall plate through the upper countersunk head high locking bolt 3; and the effective transmission of the load to the wall plate is ensured.
The lower end flanging sinking head of the 'well' -shaped web plate is simultaneously connected with the lower edge strip of the beam and the lower wall plate through a high locking bolt 5. And the effective transmission of the load to the wall plate is ensured.
Furthermore, the well-shaped web plate is also provided with a well-shaped reinforcing rib vertical to the plate surface. The stability of the reinforcing piece is improved.
Furthermore, an integrally formed inclined rib is arranged between the plate surface of the web plate shaped like the Chinese character 'jing' and the flanging. The stability of the reinforcing piece is improved, and the rigidity of the flanging is improved.
Furthermore, the reinforcing ribs shaped like the Chinese character 'jing' and the web shaped like the Chinese character 'jing' are integrally formed. The effective transmission of load is convenient, the processing and the forming are convenient, and the assembly relation is reduced.
Furthermore, the thickness of the plate surface at the joint of the 'well' -shaped web plate and the suspension support arm is 1.5-2 times that of the plate surface at the joint of the 'well' -shaped web plate and the suspension support arm. The thickness size is optimized, the connection relation is optimized, and effective weight reduction is realized on the premise of ensuring the load transfer of the suspension support arm.
The wing web is provided with a through hole, and the beam web cannot be reinforced by reinforcing structures such as a cover and the like, so that the whole reinforcing piece with the groove-shaped section similar to an H-shaped structure is designed. The reinforcement is provided with transverse and longitudinal ribs at the periphery of the through hole to compensate the weakening of the integral force transmission effect of the beam caused by the opening; in order to improve the stability of the beam web and diffuse the load outside the beam surface, the reinforcing part is designed into an integral structure. This form reinforcement will hang support arm, roof beam and wallboard and connect, fine assurance load is effectively transmitted to the wallboard.
The design form effectively completes the reinforcement of the beam web through holes and the diffusion of loads, the number of parts and the assembly relation are few, the structure is simple, the force transmission efficiency is high, the weight is light, and the assembly and use requirements are met.
