Abstract: The paper introduces the fundamental ideas on building the collaborative design platform of virtual visualization for sugarcane harvester. The platform is based on the globally shared product model conforming to the STEP Standard, and used PDM system to integrate and encapsulate CAD, CAE and other application software for the product development. The platform also integrated the expert system of sugarcane design, analysis and evaluation. This expert system utilized fuzzy evaluation principle to evaluate the design and simulation analysis results and make decisions. The platform provides the collaborative intelligent environment for the design of virtual sugarcane harvester prototype aiming at integrating people, process and data in the virtual product development. It also supports the customized development of sugarcane harvester series.
