Abstract
The invention discloses a kind of cargo deck stringer and block wall connection structure, including cargo deck stringer 1, jointing 2, oscillating bearing 3, the first bushing 4 and the second bushing 5, bolt 6, nut 7.Longitudinal floor beam 1 is connect with jointing 2 by bolt 6, nut 7；When jointing 2 is with wall receiving course load is blocked, cargo deck stringer 1, oscillating bearing 3, bolt 6, nut 7 will move in the slotted hole space in 2 ears chip architecture of jointing；When blocking wall receiving lateral load, cargo deck stringer 1 is rotated with the oscillating bearing 3 in 2 auricle of jointing；By the design of connection structure, cargo deck stringer 1 is avoided in course, lateral upper carrying, while also meeting bearing requirements of the cargo deck stringer on vertical.The invention avoids complicated and big weight connection structures, and the design feature of slotted hole and oscillating bearing is rationally utilized, and have many advantages, such as that structure is simple, light-weight, maintainable high.
Description
Technical field
The invention belongs to technical field of aircraft structure design, and in particular to a kind of cargo deck stringer connect knot with wall is blocked
Structure.
Background technique
Cargo deck stringer with when blocking wall and being fixedly connected, since cargo hold blocks wall complicated, the load that carries larger and stress
It is passed on longitudinal floor beam by connection structure, so that floor longitudinal beam structure stress is complicated, since cargo hold blocks the loaded deformation of wall
Cause cargo deck stringer to be deformed, increases the design difficulty of connection structure and floor longitudinal beam structure, also increase simultaneously
Construction weight.
Summary of the invention
Goal of the invention: the present invention is directed to simplify cargo deck stringer stress condition, and mitigate connection structure weight.Connection
Structure, which takes full advantage of slotted hole, has the 360 ° of rotations of motion space and oscillating bearing energy, in jointing and floor
Stringer connection side is designed as band slotted hole, and longitudinal floor beam auricle end can be moved along course in slotted hole, so as to avoid
Cargo hold blocks wall course load and passes on longitudinal floor beam；Oscillating bearing is installed in longitudinal floor beam auricle end side, avoids goods
It blocks wall lateral load and passes on longitudinal floor beam in cabin.By above-mentioned design, longitudinal floor beam stress condition simplifies, and avoids complexity
Connection structure or reinforcement structure, alleviate aero-structure weight.
Technical solution: a kind of cargo deck stringer and wall connection structure is blocked, which is characterized in that including cargo deck stringer
[1], jointing [2], oscillating bearing [3], the first bushing [4] and the second bushing [5], bolt [6], nut [7].Jointing
[2] one end is blocked wall with cargo hold and is bolted, and the other end is ears chip architecture, and slotted hole, peace in slotted hole are opened on auricle
The first bushing [4] and the second bushing [5] are filled, two bushings and slotted hole are small―gap suture cooperation；Cargo deck stringer [1] one end is
Monaural chip architecture installs oscillating bearing [3] on auricle；Longitudinal floor beam [1] and jointing [2] pass through bolt [6], nut [7]
Connection；When jointing [2] is with wall receiving course load is blocked, cargo deck stringer [1], oscillating bearing [3], bolt [6], spiral shell
Female [7] will move along the slotted hole space in jointing [2] ears chip architecture；When blocking wall receiving lateral load, cargo hold
Longitudinal floor beam [1] is rotated with the oscillating bearing [3] in jointing [2] auricle；By the design of connection structure, cargo hold is avoided
Longitudinal floor beam [1] also meets bearing requirements of the cargo deck stringer on vertical in course, lateral upper carrying.
Beneficial effect
Compared with traditional cargo hold blocks wall and the fixed connection structure of longitudinal floor beam, the invention avoids complicated and weight
The design feature of slotted hole and oscillating bearing is rationally utilized in big connection structure, simple, the light-weight, craftsmanship with structure
Good, at low cost, the advantages that being readily produced and assemble, is maintainable high.
Detailed description of the invention
Fig. 1 is cargo deck stringer and the connection structure front view for blocking wall；
Fig. 2 is cargo deck stringer and the connection structure top view for blocking wall；
Fig. 3 is to block wall jointing to bear connection structure deformation pattern when the load of course；
Fig. 4 is to block wall jointing to bear connection structure deformation pattern when lateral load.
Wherein, the first bushing of 1- cargo deck stringer 2- jointing 3- oscillating bearing 4- 5- the second bushing 6- spiral shell
Bolt 7- nut.
Specific embodiment
The present invention is described in further details below.
Cargo deck stringer [1] end monaural piece is equipped with oscillating bearing [3]；It is blocked with cargo hold jointing [2] one end
Wall connects, and opens slotted hole along course in other end ears chip architecture, and install the first bushing [4] and the second bushing bushing [5], ground
Plate stringer [1] is connect with jointing [2] by bolt [6], nut [7].Since the first bushing [4] and second [5] can be along holes
Axis sliding and slotted hole increase fitting allowance of the structure along course, so that the assembly of connection structure is simple and easy.Separately
Outside, when jointing [2] blocks wall receiving course load with cargo hold, cargo deck stringer [1] is movable in slotted hole space
, it is not deformed with jointing, therefore cargo deck stringer [1] is not subject to course load, as shown in Figure 3；Simultaneously as
Oscillating bearing [3] can 360 ° of rotations, jointing [2] with block wall bear lateral load and when deforming, cargo deck stringer
[1] jointing [2] will not be followed to move together, therefore cargo deck stringer [1] is also not subject to lateral load, as shown in Figure 4.
On vertical, since cargo deck stringer [1] and jointing [2] is tight fit, cargo deck stringer [1]
Vertical load cargo hold can be passed to by jointing [2] and block on wall web.
