[Abstract]:With the rapid development of modern industry, the speed of product upgrading is also gradually speeding up, and the market competition is becoming more and more intense. Enterprises should try their best to speed up the time to market under the condition of ensuring the design quality of products and increasing the variety of products. Reduce the design cost of the product. The application of rapid design technology has become one of the effective means for enterprises to improve the efficiency of product design. The combination of modularization and parameterization is an effective way to achieve rapid design. This paper takes the bridge crane as the research object, according to the demand of the user, the function and the structure characteristic of the bridge crane, in order to improve the design efficiency of the product and enhance the competitiveness of the product, the modular and parametric design technology is used. The rapid design system of bridge crane is developed, and the part-whole machine of bridge crane is designed quickly. The main contents of this paper are as follows: (1) the development characteristics and current situation of bridge crane at home and abroad, the development status of parameterized technology and the research situation of rapid design are studied. The background and significance of this research are given. (2) the theory of rapid design is discussed, and the modular and parametric design methods are described. The combination of modularization technology and parameterized technology is analyzed to provide a theoretical basis for the next rapid design of bridge crane. (3) the key technology of bridge crane rapid design system is studied. It includes modularization technology, parameterization technology, secondary development technology of SolidEdge and database technology. The function structure diagram is constructed by axiomatic design theory to divide the module of bridge crane. Parametric modeling technology of bridge crane parameterization technology, parameterized model driving technology and parameterized model assembly technology. (4) taking VB6.0 as programming tool and Access as system database, the second development of SolidEdge is carried out. The rapid design system of bridge crane is developed, and the main functions of the system are described in detail. The product design process of "new contract, parameter setting, component calculation and checking, model module selection and driving-model modular assembly-model rendering-whole machine product" is realized.
