3d Parametric Modeling And Data Management Technology Based On Model Definition

This article describes a suitable for the plane model definition (MBD) based on thetypical parts of the fast modeling method of data and methods of management, thismethod is the national defense "twelve. Five" pre-formulation part of key projects.As the era of rapid development and the modern science and technology progress,the world the plane design manufacturing market increasing competition，the enterpriseis to shorten the design development time as the current goal. The plane parts have tens,and most of the parts similar, the structure is complex,repeat design these aircratf partstime-consuming consumption force, so how to design aircratf parts of fast typical is animportant question. This article mainly introduced the theoretical support andrealization means, to the plane of the typical parts as the research object，and analysesthe MBD technology in parts of modeling process feasibility and concrete usage, and inCATIA under the environment of the CAA second development by its tools,a driver canquickly generate new aircratf parts of parameterized modeling methods, and use theinteractive way realization of aircratf parts MBD parameters of the typical informationto read, MBD template of the establishment and MBD parameters to delete modification,drive to produce new MBD parts model, and management aircratf parts in the process ofmodeling data and related information, and to realize the MBD3dimensionalparametric model of data management. In this paper, based on the plane to MBD typicalparts of characteristic parameters read, reorganizes the classiifed，user can chooseaccording to the actual demand MBD parameter information, establish MBD template,and realize the template for MBD upload read, and to select MBD parameters changed,to assign a value to drive fast generation new aircratf parts, design using Excle designtable and oracle database in aircratf parts such as data information for the wholemanagement,greatly shorten the design time, improve the design efficiency.
