Embodiment Construction

[0025] The specific implementation process includes:

[0026] 1. According to the MBD-based labeling specifications and inspection requirements, the relevant inspection information including the 3D model is automatically obtained through software identification technology.

[0027] 2. By acquiring and integrating the inspection information and associating the geometric features of the 3D model, the definition of the 3D inspection model based on MBD is completed.

[0028] 3. According to different testing requirements, select the appropriate testing methods and testing tools, and complete the formulation of a testing process.

[0029] Repeat the above process, plan the detection sequence according to the sequence of the detection process, and realize the definition of the measurement process. According to the defined measurement process, the measurement plan is generated, and according to the measurement plan, the corresponding three-coordinate measurement equipment is selecte...

Abstract

The invention belongs to the field of aircraft digital manufacturing, and relates to an MBD-based aviation complex structural member inspection method, which comprises the following steps: step 1, acquiring three-dimensional inspection model information; step 2, planning and inspection path; and step 3, three-coordinate measurement and inspection. According to the invention, a software secondary development technology is used; a computer identification technology is adopted to replace manual inspection in the inspection process, three-dimensional labeling information and associated geometricalinformation of a part are directly detected through feature identification of a three-dimensional model by software, geometrical features to be detected and detailed geometrical information of the geometrical features to be detected are obtained, and then a measurement program is generated through detection planning to complete product inspection.

Description

technical field [0001] This software invention belongs to the field of aircraft digital manufacturing. It is mainly aimed at the inspection of aviation complex structural parts based on MBD. It is used to solve the problem of being able to directly identify and obtain the inspection information on the 3D model in the inspection process based on MBD. It no longer uses 2D engineering drawings as the inspection basis, which saves time and is efficient. The application effect of getting twice the result with half the effort. Background technique [0002] With the development of aircraft manufacturing technology, my country's aviation manufacturing enterprises have fully implemented full 3D MBD (Model-Based Definition), which is to jointly define 3D product design information and manufacturing information into the 3D numerical model of the product, and directly use the 3D annotation model as the manufacturing model. and inspection basis, changed the original three-dimensional des...
