The Research And Design Of Rolling Bear Database And CAD System

With the development of computer science and CAD, a lot of design works gradually tends to be automatic and intelligent, which can save time and improve efficiency. As one of the most basic parts, rolling bearing has extensive application, so the selection and design have become an essential part of mechanical design. What's more, a lot of charts and formulas need to be utilized during the design process, so that designers need to consult information and calculate formula repeatedly which will increase the workloads. Therefore, the computer technology can be applied to the design of rolling bearings, which not only can reduce the workload of designers and make them have more time and energy to launch a new product, but also can improve the efficiency and correctness of design.Aimed at this problem, a rolling bearing CAD design system based on VB language and SolidWorks software with practical value to some extend has been developed in this paper. This system can realize knowledge query, intelligent selection, checking calculation, 3D modeling, optimization design and other functions, which can make the design process of rolling bearings more quickly.In this paper, the main works are as following aspects. Firstly, the design scheme and development process is determined and the rolling bearing database is created through researching the domestic and overseas development status of the rolling bearing CAD design system and analyzing the knowledge of rolling bearing design. Secondly, the overall design of the rolling bearing selection system is completed which realize the fast design of the selection of rolling bearing with fuzzy theory. Then combining with the verifying calculation, the automatic development of working life checking in different cases including single rolling bears and pairs has been completed. Using the knowledge related to secondary development of SolidWorks, complete the design of 3d modeling module. Finally, the parameter optimization design of non-standard bearing has been completed with the optimization calculation method of SCDD which can solve the mathematical model, and the optimization design has been realized by developing program.In this paper, the rolling bearing CAD design system can be used as the calculation and query tools in the rolling bearing designing, which not only can improve the efficiency and calculation accuracy of the staff, but also can play a positive role in promoting the development and popularity of design system for rolling bearing.
