As the core of automotive welding production line, the development speed and quality of automotive welding jig impact on the automobile production cycle and manufacturing precision directly. At present, the traditional design method of automotive welding jig is difficult to adapt to the developing speed of auto body. In order to improve the design efficiency of the welding jig, a rapid automobile welding jig design method based on parametric technology is developed in this paper. Supported by parametric theory, combining with CATIA secondary development approach, the principle and structure of the automobile welding jig rapid design system are presented, and related key technologies in rapid design system developing are studied deeply, and a rapid welding jig parametric design system is developed finally. Taking one station of rear side member for example, the generation process of automotive welding jig is analyzed in detail, and design practice shows: the welding jig designed by this system has shorter development cycle then the traditional method.

The traditional shape design method of tractor is mainly completed based on the manual design. Messages are transmited mainly through material object, model, blueprint and template. The material object and model even have a small change that will cause massive chain-reactions such as tedious blueprint revision. And there will be a great many of problem, such as the development cycle of tractor to be long, the accumulative error of design to be big, the development cost to be high and product universalization and serialized degree to be low. This problem is key problem to be solved for shape designer. Advanced design method such as CAD/CAM provid solutions for us, and especially the concept of parametric design was applied. In this paper an appfoach for the parametric design of tractor configuration will be presented. To this end, there are two key issues to be solved: First, the parametric representation of the tractor configuration, second，how to generate a three—dimesional shape of the tractor automatically based on the parametric representation. The parametric design of the tractor configuration is implemented by making use of the API technique of the CAD software，namely automation in CATIA．The test example shows that the approach presented is able to generate a three dimensional shape of the tractor automatically and meet the need of the parametric design of tractor configuration.

Traditional agricultural machinery design methods usually go through longer-design cycle and can hardly make good use of existing knowledge and experience. In view of this problem, parametric design theory and knowledge-based engineering were applied to the disc-scoop-type metering device designed to improve the design experience and reuse design knowledge. Through the knowledge-based parametric design method, the design framework model of disc-scoop-type metering device was put forward. The knowledge library on the basis of design rules and characteristic similarity-based case library were created, and disc-scoop-type metering device parametric design system based on knowledge had been developed on the platform of Pro/Engineering. The rapid design for knowledge-driven model of disc-scoop-type metering device was realized. The specific design examples clearly indicated that the establishment of the system considerately improved the quality and efficiency of the design.
