[Abstract]:At present, the crane industry in our country has great development potential and good prospect. As the most widely used lifting and transportation machinery, bridge crane is used in machinery, metallurgy, traffic, mining workshops, warehouses, indoor or outdoor fixed intercropping loading and unloading. Handling and lifting work. It is a necessary mechanical equipment for the factory interior logistics system. But at present, the design method of bridge crane in China is not perfect. The research work of this paper is to improve the design level of the bridge crane and to realize the programming of the scheme design process of the general bridge crane. The purpose of this paper is to liberate designers from a lot of tedious and repetitive work, and to improve the efficiency and quality of crane scheme design. According to the working characteristics of the general overhead crane mechanism and structure, this paper makes a comprehensive, systematic and in-depth study on the scheme design of the general bridge crane, and combines with the modern design method. The general bridge crane scheme design system is studied. At the same time, with Visual Studio 2005 as the system development platform and VB.NET as the development language, the special software for the general bridge crane scheme design is developed. The main work of this paper is as follows:. 1) the research of the general bridge crane scheme design system. The content of the general bridge crane scheme design is deeply studied, and the design calculation method and the design flow chart of the scheme design are determined. Based on GB/T 3811-2008, the allowable wheel pressure table of wheel and track is reworked out for the determination of wheel diameter and track. The calculation method of the economic beam height of box beam section is studied. The calculation formula of the economic beam height of the main beam is rededuced. The derivation process is clearer and easier to understand. At the same time, The economic beam height determined by the strength condition and the economic beam height determined by the stiffness condition have a unified form and are more convenient to use. The finite element parameterized modeling and analysis technology based on APDL is studied to realize the finite element calculation of the main beam. 5) the research and development of the general bridge crane scheme design system. The design process of the general bridge crane mechanism and main beam is studied, and the function is divided, each function module is determined, and the system frame is constructed. The data information involved in the general bridge crane design is analyzed and the database design is completed. The general bridge crane scheme design software is developed by using the object oriented programming method. In this paper, the design example of 200 / 50 t bridge crane is used to verify the scientificity and practicability of the system. The results show that the system can complete the scheme design quickly and form the scheme book only by inputting the basic parameters. The design cycle is shortened greatly and the design efficiency is improved.
