复杂产品虚拟装配过程模拟与装配质量预测技术

ccording to the requirement of shop-floor and the development of virtual assembly technology, an integrated assembly process simulation method including assembly precision, physical character, cable harness and tube assembly simulation is put forward, and the workflow of this method is introduced. The information integration method between CAD system and virtual assembly system based on standard model data, flexible cable harness modeling and routing technology based on discrete control point, product tolerance model and assembly precision pre-analysis technology in virtual environment are researched. Lastly, it points out that virtual assembly technology can take full advantage of the experience and apperception of human, so as to realize the assembly simulation for all kinds of problem in shop-floor from process and physically based modeling view, as well as providing a way for realization complex product’s scientific assembly and assembly quality prediction.
