Structural and Logical Design Solution Class Generalization With the Use of Design Procedures Representation Adapted Functionally 000_9.pdf

Design of modern products relating to different subject areas and consisting of a large number of components differs by the presence of the technical requirements to the entire product without separate requirements to its components. The design activity results include complete design documentation and product assembly 3D-model. The process of assembly 3D-model formation includes adding 3D-models of components and establishing conjugations between them. In order to construct, correct, and maintain (update or modify) a 3D-assembly, rebuilding should be provided. Typically, the process is carried out through manually handling of parts parameters and conjugations. That requires additional time and labor expenses. The authors propose the solution of the problem in establishing the structural and logical relationships between the components of the assembly 3D-model on the attribute level allowing to link the components and structural objects. Interrelations between the components allow not only to determine their location and link to each other operating with design parameter values but also to modify the design solution without violating its integrity that is not ensured by any modern cAD-system.

Representing Design Process By Generalizing Elementary Operations to Semantic Unit Level 000_11.pdf

The design process can be represented by the system of project procedures described in the IDEFx methodology. That allows to decompose it into design stages. Design stage is a sequence of design solution formation actions. Such sequence consists of project operations or procedures and has completeness in terms of getting an object or its fragment with real semantic content (physical meaning). Each stage is strictly defined in terms of either its execution order or the input and output data that makes it impossible to change them and preserve the overall structure correctness of the design solution formation. The authors research the model of project activity processes representation with the use of the introduced concept of the design stage as a semantic unit and Open CASCADE Technology. The researches examine a lot of design conditions and limitations. On the basis of such conditions and limitations, with the use of Open CASCADE Libraries, the system of project procedures was developed. The software implementation of these procedures can provide the modifiability of project stages. Therefore, the representation of design process allows to accumulate, generalize and modify the process of design solution formation preserving the completeness of both the process and design solution.
