Operation description parameterized generation method for aircraft assembly

Abstract

The invention discloses an operation description parameterized generation method for aircraft assembly. The method comprises the following steps: summarizing and classifying typical operation description; performing attribute definition on the typical operation description; performing parameter definition on the typical operation description; obtaining operation description from a parameterized operation description library; substituting a parameter part in the operation description; storing generated operation description. The method assists technologists to rapidly find out an operation description template by performing classification and key attribute definition on the operation description, guides the technologists to edit operation description and improves the normalization and reasonability of technical files by performing parameter definition on the operation description, realizes rapid selection and filling of the parameter part by obtaining a resource name in a manufacture resource library and all resource names in process links where the technologists are located, can automatically store the edited operation description in a corresponding position of a process, is convenient for subsequent calling and processing of the operation description, and improves the work efficiency.

Description

Technical field [0001] The present invention relates to the technical field of digital assembly, and more specifically relates to a parametric generation method of operation description for aircraft assembly. Background technique [0002] Assembly instructions are technical documents that define the content and specifications of assembly work. A large number of assembly instructions are required to guide the assembly work during the aircraft assembly process. The preparation of assembly instructions is an important link in the aircraft assembly process, which has an important impact on improving product quality and shortening the manufacturing cycle. The main part of the assembly instruction is a large section of the operation description, so the most important task of compiling the assembly instruction is to edit the operation description. In the aircraft assembly process, the operation descriptions of a large number of procedures are often similar, that is, a considerable part...

AI Technical Summary

Problems solved by technology

[0004] (1) Heavy workload, waste of time and manpower

If a craftsman wants to modify the existing operation description to generate a new operation description, he first needs to spend a certain amount of time and effort to find the required operation description, and then he needs to read the operation description carefully and make a review of the content that needs to be changed. Modifying one by one, the whole process is time-consuming and laborious

[0005] (2) Requires rich experience of craftsmen

Before editing the operation description, the craftsmen first need to have a relative understanding of the assembly process of the structure in order to find a similar operation description; and directly modifying the existing operation description is also a very empirical work. If the craftsmen do not have a certain level of knowledge, the operation descriptions edited by them are prone to errors

[0006] (3) The generated operation description is not standardized enough

Due to the different levels of knowledge and language habits of different craftsmen, even for a specific process in the same structural assembly, the operation descriptions edited by them may be quite different, which will bring many reading obstacles to other staff. It takes time to understand the different expressions, which is not conducive to the overall aircraft assembly work

[0007] (4) The generated operation description may have missing or wrong changes

If a certain operation description wants to be applied to the assembly of another structure, there are often more than one places that need to be modified, and a certain word in the operation description may appear multiple times, which requires the craftsman to replace all of them with new ones that are suitable for the new structure. The relevant words of the structure, and the artificial modification method will inevitably lead to the omission of the words that need to be modified or the modification of the words that should not be modified
