Abstract: In order to improve the design efficiency of the crane and its parts to meet the fierce market competition, we developed rapid design system for crane drum. According to GMD theory, this paper takes crane drum for study, and divides it into several modules to form series and modular of crane drum. Summarized the design theory and knowledge of the crane drum and determined the parameters of functional modules. We shift modules from static modules to dynamic modules. By making a second development of Solid Edge with Visual Basic.NET, we developed agile design system for crane drum. After numerous tests in the actual design process, the system can greatly improved the quality and efficiency of design.

Abstract: Though rule-based reasoning system is easy to create and convenient to extend, it is not flexible because of the demand for precise matching. Geometric reasoning system can obtain engineering semantic from CAD model and connect geometric topology with design knowledge, but it can not drive product design directly. Utilizing the complementary of rule-based reasoning and geometric reasoning, a product design method based on integrated geometric and rule-based reasoning is presented. The method can standardize the expression of design scheme which is from geometric reasoning, and dock seamlessly design scheme and input condition in rule-based reasoning system. Furthermore, the result of rule-based reasoning can drive product design directly. The operation of human-computer interaction and designer’s experience needed are decreased greatly. Digital target in locater is significant to harmonize aircraft tie-in. there are different types in it, and the amount of it is huge, so its design process is complicated and fussy. On the basis of the method, a rapid design software package for locator digital target design is developed and has been applied in aircraft assembly tooling design. The application has proved the method can improve design efficiency, standardization and intelligence.
