Embodiment Construction

[0052] It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0053] Aiming at the problem that the existing process holes lack the process design method of the systematic process design method, the present embodiment proposes a process hole design method, device, equipment and storage medium. The specific ideas are as follows:

[0054] By obtaining the load of the target process hole 2, according to the thickness of the boss 5 and the load, the stress of the target process hole 2 is obtained, and the target thickness of the boss 5 corresponding to the stress satisfying the strength condition is obtained; And according to the stiffness information set, the standard height and standard thickness of the stiffener 6 when the stiffness meets the stiffness conditions are obtained.

[0055]In the existing process design process of the process hole, it mainly relies on the ex...

Abstract

The invention discloses a process hole design method, device, equipment and storage medium, including S10, obtaining the load of the target process hole; S20, obtaining the stress of the target process hole according to the thickness and load of the boss; S30, judging Whether the stress satisfies the strength condition; if not, adjust the thickness of the boss, and return to step S20, cycle until the stress meets the strength condition, and obtain the target thickness of the boss; S40, according to the stiffness information set, obtain the reinforcement when the stiffness meets the stiffness condition The standard height and standard thickness of the rib; the stiffness information set includes the stiffness of the target process hole corresponding to the rib at different heights and different thicknesses. A clear standard is put forward, and the technological design scheme of this scheme forms a unified design standard, so that the technological holes processed by this scheme can meet the rigidity and strength, and at the same time, the technological design efficiency of the holes can be improved.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to a design method, device, equipment and storage medium for a process hole. Background technique [0002] When assembling aircraft parts, in order to meet the process requirements, it is necessary to open different kinds of process holes on the skeleton to realize different functions. Among them, the process holes designed to realize the support and positioning function are often due to the strength when bearing a large load. Or insufficient rigidity will cause local deformation, which will affect the assembly and positioning accuracy of the entire component. Therefore, when designing the skeleton process hole, the local strength and rigidity of the process hole must be guaranteed. [0003] At present, the process design of the process holes of the aircraft skeleton mainly depends on the experience of the assemblers, and there is a lack of systematic process design method...
