Storage method of solid data integrating shape and physical characteristic

Abstract

There is disclosed a method of storing substantial data integrating shape and physical properties comprising an external data input step (A) for inputting external data 12 consisting of boundary data of an object 1, an Octree division step (B) for dividing, by Octree division, the external data into cubical cells 13 which boundary surfaces are orthogonal to each other, and a cell data storage step (C) for storing the values of various physical properties for each of the cells. Furthermore, in the Octree division step (B), each of the divided cells 13 is classified to internal cells 13a located in the interior of the object, external cells 13b in the exterior thereof and boundary cells 13c including boundary surfaces. Thereby, substantial data integrating shape and physical properties can be stored in small storage capacity, whereby it is possible to manage shape, structure, physical-property information, and history of matter in a unified way, and to manage data associated with a series of processes of from design to work, assembly, test and evaluation under the same data, thus enabling the integration of CAD and simulation.

Description

Technical field [0001] The present invention relates to a storage method for storing entity data of comprehensive shapes and physical characteristics with a small storage capacity, and for storing entity data that can unify CAD and simulation. Background technique [0002] In the cutting-edge research and development and technology development sites, as it becomes more advanced and complicated, huge trial and error will inevitably occur, which increases the risk in development. As a country with the goal of building a nation based on science and technology, it is very important for my country to eliminate these risks as much as possible to achieve advanced and efficient development process innovation. [0003] Now, in the field of research and development and technology development, CAD (computer-aided design), CAM (computer-aided manufacturing), CAE (computer-aided engineering), CAT (computer-aided testing), etc. are used for design, processing, analysis, Simulation means of exp...

AI Technical Summary

Problems solved by technology

[0010] (1) The data is not transferred, and the internal conversion operation is weak (problems with numerical errors and processing methods)

[0011] (2) Not directly used for simulation (because the internal information is not obtained, so the grid is generated)

[0012] (3) Research on CAM processing is not possible (only the final shape)

[0014] (1) The processing process cannot be represented (the support for rough processing or process design is insufficient)

[0015] (2) Not compatible with new processing methods such as laser processing and ultra-advanced processing (only cutting, data accuracy is not enough)

[0016] (3) The processing method itself cannot be selected (the composite has internally different material properties)
