Method for achieving MBD manufacturing model of integral structure parts based on synchronous modeling technology

Abstract

The invention provides a method for achieving an MBD manufacturing model of integral structure parts based on synchronous modeling technology and belongs to the field of computer aided design. The method includes the steps of S1, creating an MBD design model: exporting the design model as a lightweight file in step format, importing 3D mapping software that supports synchronous modeling, exportingthe design model as a file with a suffix name of .prt, and re-opening the file with the suffix name of .prt to perform MBD marking; S2, creating an MBD process model: performing feature complement onthe MBD design model in reverse order through a synchronous modeling method, and performing sorting and grouping on complementary features; copying MBD design information in the MBD design model by groups to a corresponding layer of each process, and adding new additional process annotation information to the corresponding layer of each process; S3, creating an MBD detection model: enter a working environment of the MBD design model, operating a physical process model to return to the design model, creating a new detection layer, storing MBD detection process information to the detection layer, and ordering the detection sequence through labels.

Description

technical field [0001] The invention relates to the technical field of computer-aided design, in particular to a method for realizing the MBD manufacturing model of integral structural parts based on synchronous modeling technology. Background technique [0002] MBD (Model Based Definition, model-based definition) technology emphasizes the definition based on the 3D model, which includes the basic dimensions, tolerances, non-geometric information, annotations, etc. of the model. Compared with two-dimensional drawing information transmission, it has the advantages of fast, accurate and intuitive. When the 3D model changes, the related dimensions will be driven and updated, which cannot be realized in the 2D environment, so that the ambiguity in the transmission of dimensional information can be eliminated. At present, foreign SIEMENS, PTC, etc. are based on knowledge and integrate process modeling / planning / analysis / simulation to form an integrated integrated platform. Among...
