[Abstract]:Firstly, based on knowledge engineering, this paper analyzes the current research status of knowledge engineering technology at home and abroad, and on this basis, combined with the requirements of modern product design for KBE system. With the dynamic knowledge base organization technology as the breakthrough point, the goal is to optimize the knowledge engineering system and improve the automation intelligence. A great deal of research has been done on the optimization technology of product design of KBE system. The main research work and innovation of this paper are summarized as follows: 1) three layers of interface layer, control layer and data layer are put forward to realize the design method of shaft parts based on knowledge. At the same time, the realization methods of each layer are put forward. Namely: using C#.NET and UGopen MenScript to realize interface layer development. C#.NET and NX Open APIs NX are used to realize the development of control layer and SQL Server2005 database to realize the development of data layer. The key technology of knowledge driven shaft part design based on C#. net SQL database and NX software platform is solved. This paper summarizes the design experience and modeling characteristics of shaft parts of several aero-engine models and helicopter transmission system models. Taking dynamic knowledge base as the core, the development technology of NX, SQL2005 and #.NET is used. The prototype design system of shaft parts is constructed to improve the organization structure of knowledge base and improve the running efficiency of knowledge system with dynamic modular organization technology. In order to realize the automation and intelligent improvement of the whole system, the feasibility of the theoretical research in this paper is verified by the development of the actual shaft products. The research results have been applied in the model and greatly improve the design efficiency of shaft parts.
