Abstract


Parametric design method is efficient and practical. It has great application value in the series design, similar design of products, and special CAD system development. Compared with traditional design method, it can decrease the repeated work and improve the design efficiency, accords with modern product design demand. As a transmission mechanism, reducer has been applied widely. Considering its similarity of structure and repeatability of design, it is suitable for the parametric design method. On this background, combining with the subject of "character state space model and integrated system of mechanical product intelligent design", this paper studies the parametric design method based on Pro/E, establishes a reducer parametric design system, and discusses the topology optimization of a reducer box.Firstly, general methods of Pro/E secondary development based Pro/Toolkit is studied, including program interface, Pro/Toolkit menu, calling UI dialog, MFC dialog, resource files and registration, running of application program. These are key technologies of establishing product parametric design system. Database access technology is studied to realize data exchange between Pro/Toolkit program and SQL server.Secondly, models and assemble templates are created by parametric modeling and program method, based on which parametric design is realized combining with parameter drive program. A reducer parametric design system is established, including part design module and standard part module and so on. It could be used to design a one-stage cylindrical gear reducer, accomplish the whole process of gear design, shaft design, gear strength check and main parts modeling and assemble. And a standard part library is created.At last, topology optimization of a reducer box is discussed. According to the practical force condition, the reducer box structure is improved based on static analysis and topology optimization analysis.The parametric design method based on Pro/E studied in this paper has generality, and could be applied to the design of other products; the application of the reducer parametric design system and topology optimization method has certain significance to improve the design efficient and quality.
