Description
Technical field
The invention belongs to technical field of aircraft structure design, and in particular to a kind of L-type hair for engine connection structure
Motivation hanging joint.
Background technique
Engine hanging is the important force transferring part for connecting aircraft wing and nacelle, and the load born is big, load working condition
More, the jointing of hanging and other structures is all design difficulty all the time；Existing structure is mostly common auricle structure,
Very big concentrated stress can be generated when transmitting biggish concentrfated load, so that connector is easy to happen destruction.Traditional auricle directly with quilt
Connection structure is connected, and very big stress can be generated when transmitting biggish concentrfated load, auricle is caused to be easily destroyed.
Summary of the invention
Goal of the invention: proposing a kind of L-type engine hanging joint, and inadequate to solve existing structure intensity, easy to damage asks
Topic.
Technical solution: a kind of L-type engine hanging joint, including auricle structure, diffusion structure and reinforced structure；Wherein,
Auricle structure is such as connect by strut with wing, for transmitting load, diffusion structure is for making for connecting with other structures
Biggish concentrfated load is diffused on each region of connection connector, reduces the stress level of connector, reinforced structure is used for
Reinforced joint intensity improves connector service life, while can be used for transmitting the load perpendicular to auricle plane, reinforced structure with
Diffusion structure is integrally formed, and for the diffusion structure shaped like L-type, the reinforced structure is to increase rib, muscle on strengthening region surface
Item is perpendicular to auricle plane.
The diffusion structure angle is variable.
Diffusion structure and reinforced structure are made of aluminum alloy materials.
The earhole of the auricle structure locally uses titanium alloy material.
The rib width for changing reinforced structure can bear different size of lateral load.
Nail hole is provided on the diffusion structure, the magnitude of load that nail hole quantity can be born according to connector changes.
Advantageous effects: joint structure proposed by the present invention is simple, and good manufacturability, posting is efficient, and the service life is long；It is using
In the process, the stress of the structure is in a very low level always, and posting effect is good.Simultaneously because diffusion structure can be by load
Dispersion transmitting, so that the other structures connecting with the connector are also able to maintain a lower stress level.
Detailed description of the invention
Fig. 1 is engine hanging joint structural schematic diagram；
Wherein, 1- auricle, 2- diffusion structure, 3- reinforced structure.
Specific embodiment
Referring to attached drawing 1, the invention proposes a kind of L-type engine hanging joints, including auricle structure (1), diffusion structure
(2) and reinforced structure (3)；Wherein, auricle structure (1) is such as connect with wing by strut, is used for connecting with other structures
Transmit load, each region that diffusion structure (2) is used to that biggish concentrfated load to be made to be diffused into connection connector reduces
The stress level of connector, reinforced structure (3) are used for reinforced joint intensity, improve connector service life, while can be used for transmitting
Perpendicular to the load of auricle plane, reinforced structure (3) and diffusion structure (2) are integrally formed, the diffusion structure (2) shaped like L-type,
The reinforced structure (3) is to increase rib on strengthening region surface, and rib is perpendicular to auricle plane.
On the basis of above structure, to adapt to different hanging objects, diffusion structure (2) angle can change therewith.
On the basis of above structure, for the weight of limited mitigation structure, diffusion structure (2) and reinforced structure (3) are equal
It is made of aluminum alloy materials.
On the basis of above structure, the earhole edge of auricle structure (1) uses titanium alloy material, to further increase ear
Piece intensity.
On the basis of the said structure, in actual application, the rib width for changing reinforced structure (3) can bear difference greatly
Small lateral load；Reinforced structure is provided with lightening hole, further to mitigate the weight of connector.
On the basis of above structure, nail hole, the load that nail hole quantity can be born according to connector are provided on diffusion structure (2)
Lotus size changes.
Claims (5)
