Research on series crane’s rapid designing based on knowledge integration

Aimed the issue of series product innovation lower and repeated designing,rapid designing based on knowledge Integration was presented. According to the trait of bridge structure of Overhead Traveling Crane,design system,design process,and design methods was researched. By analyzing the bridge structure coding knowledge and module interface knowledge,the main modular design structure and configuration design structure was summarized. On the basis of holographic modeling,combined with process knowledge,database knowledge,document knowledge and so on to express and get knowledge,the Way of integration was adopted with assembly draft,assembly equation set and constraint set,and Knowledge integration model including parameter-driven was established. With the help of technology of modularization and parameterization,the bridge structure knowledge reuse and series product rapid designing was realized. The results showed that this method better meets the demand of practical application.
