THE RESEARCH OF THE HIERARCHICAL STRUCTURE CHARACTERISTIC MECHANICAL PRODUCT CONCEPTUAL DESIGN BASED ON GENETIC ALGORITHMS

摘要

Conceptual design is a vital aspect of design process. The quality of product is directly influenced by Conceptual design. The science and technology rapid development, the product function request increases day by day, the complexity increases, the average life reduces, the renewal speed speeds up. However, conceptual design, in particular mechanical product conceptual design method, then appears lacks the ability, cannot follow time the need to develop. This article in analyzes the hierarchical mechanical product structure characteristic in the foundation, in view of had the hierarchical structure characteristic mechanical product the holistic conceptual design to propose the hierarchical gene code technology, and in the knowledge evolution algorithm - genetic algorithms foundation, the genetic algorithms and the mechanical product holistic conceptual design will unify, proposed face the hierarchical structure mechanical product holistic conceptual design genetic algorithms CAD design model. According to this design model, applied the Visual C++6.0 and the SQL-Server2000 database software and has completed facing the hierarchical structure mechanical product holistic conceptual design genetic algorithms in the numerical control lathe holistic conceptual design practical application system development. Has established the numerical control lathe holistic conceptual design system, this system can complete the numerical control lathe holistic conceptual design, obtained the good result through the actual use.
