[Abstract]:The structural design of mechanical elastic wheels is a very concrete and complex process. It is very important to introduce parametric design into the design of mechanical elastic wheels for improving its design efficiency.Based on the theory of parametric design and Pro/E secondary development, this paper combines the structural characteristics of mechanical elastic wheels.A structural parameterized design system (ME-Wheel Design) for mechanical elastic wheels is developed. The functions of parameter selection and verification, 3D modeling, drawing of engineering drawings and automatic assembly of new type mechanical elastic wheels matching with traditional tires are realized.The main research work of this paper is as follows: (1) referring to the traditional tire design process and combining the structural characteristics of mechanical elastic wheels, the overall design framework of ME-Wheel Design system is built, which mainly includes overall design, bead design, hub design, etc.Based on the software development platform Visual Studio 2008 and Pro/E 5.0 secondary development environment, and using Access 2007 to build the background database of the system, the program development of ME-Wheel Design system is completed, which is based on the simplified mechanical analysis model of mechanical elastic wheel.The mechanical analysis of each part of the mechanical elastic wheel is carried out, and on this basis, the strength of the key parts is checked, and the top-down design principle is used.The structural parameters of the wheel are classified and the constraint relations between the structural parameters are established, and the mechanical elastic wheel parameter selection and checking function including the visual interface is realized based on MFC technology, which simplifies the original complicated calculation process.The background database of the system is built and the integrated management of design parameters and design specifications is realized by using ADO database access technology. The parametric design of mechanical elastic wheel is studied and realized based on Pro/Toolkit toolbox.Based on the parameterized modeling method, the parametric model base of mechanical elastic wheel is built, and the relation between the system and the parametric model base is established by using the API function of Pro/Toolkit toolbox to realize the 3D modeling of mechanical elastic wheel parts.Based on ME-Wheel Design system, the parameterized structure design of a new type of mechanical elastic wheel matching with 265/70R17 car inflatable tire is realized.The system has been tested successfully.The results show that the system can standardize the design flow of the mechanical elastic wheel, and can realize the rapid change of the mechanical elastic wheel more reliably.Moreover, the development of ME-Wheel Design system with perfect data management function and friendly man-machine interface is the exploration of digital design and manufacture of mechanical elastic wheel, which is of practical significance to improve the design efficiency of mechanical elastic wheel.Moreover, the idea of design and development has certain guiding significance for the development of other product design systems.
