Abstract
The utility model belongs to the design technology of wing structures and in particular relates to a novel diffusion member of concentrated loads between wing ribs. The novel concentrated load diffusion member is characterized by comprising two inclined ribs and a transverse rib which form an inverted triangle structure, wherein a vertical rib is arranged between an intersection position of the two inclined ribs and the transverse rib and is particular to the transverse rib. The structure in simple in design form, liable to design and analyze and convenient to process, is provided with a direct force transferring path, belongs to a self-balancing structure, can effectively prevent the concentrated loads between the ribs from causing out-plane loads on the wing ribs so as to prevent a dangerous part from being transferred from a lower wall board to the wing ribs, is light in weight and lighted than a diffusion member in a short-beam form by more than 30% and is simple in assembly; the number of fasteners is effectively reduced, and the assembly time is saved.
Description
Technical field
The utility model belongs to wing structure designing technique, is specifically related to a kind of wing intercostal concentrated load diffusion part.Background technology
Limited by total arrangement and structural arrangement, the concentrated load point of action on wing, as hanging hitch point, wing flap hitch point etc. conventionally can not be just to diffusion structures such as the rib in wing box, long purlins, but between two ribs.Now, must design special diffusion structure the concentrated load transmitting from hanging, wing flap is diffused on rib, and then be diffused on wing box.Current solution is the diffusion part that adopts short beam form.The diffusion part of short beam form all has application in A320, A340, can bear larger load, short beam is connected with two side rib webs, area of contact is large, concentrated load can be reached on rib web more uniformly, the face Moments that concentrated load causes in rib plane, by short beam upper end horizontal bar balance, is beneficial to rib stressed, shortcoming is complex structure, and weight is large.
Utility model content
The purpose of this utility model is: propose a kind of version simple, Path of Force Transfer is direct, and assembling amount is little, lightweight wing intercostal concentrated load diffusion part.
The technical solution of the utility model is: a kind of wing intercostal concentrated load diffusion part, it is characterized in that, comprise two diagonal bars and a horizontal bar, two diagonal bars and a horizontal bar form inverted triangle structure, a perpendicular muscle is set between two diagonal bar position of intersecting point and horizontal bar, and this perpendicular muscle is vertical with horizontal bar.
The cross sectional shape of described diagonal bar, horizontal bar and perpendicular muscle is " work " font.
At described two diagonal bars and horizontal bar intersection, side plate is set.
In described Liang Tiao diagonal bar intersection, base plate is set.
Diagonal bar, horizontal bar, perpendicular muscle, side plate and the base plate of described wing intercostal concentrated load diffusion part are integrated machine add-on type.
The beneficial effects of the utility model are:
1) version is simple, and Path of Force Transfer is direct, is easy to design analysis, is convenient to processing;
2) the utility model belongs to self-balance structure, can effectively avoid intercostal concentrated load on rib, to cause face external load, has avoided dangerous position to be transferred on rib by lower wall panels;
3) lightweight construction, spreads part energy loss of weight more than 30% compared with short beam form;
4) assembly relation is simple, effectively reduces fastener number, saves time of setting up.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of wing intercostal concentrated load diffusion part, is characterized in that, comprise two diagonal bars and a horizontal bar, two diagonal bars and a horizontal bar form inverted triangle structure, and a perpendicular muscle is set between two diagonal bar position of intersecting point and horizontal bar, and this perpendicular muscle is vertical with horizontal bar.
The cross sectional shape of described diagonal bar, horizontal bar and perpendicular muscle is " work " font.
At described two diagonal bars and horizontal bar intersection, side plate is set.
In described Liang Tiao diagonal bar intersection, base plate is set.
Diagonal bar, horizontal bar, perpendicular muscle, side plate and the base plate of described wing intercostal concentrated load diffusion part are integrated machine add-on type.
