Abstract: To avoid the hidden dangers of design and to achieve rapid processing of whole design process,a driven strategy of step-up level based on product life cycle knowledge was proposed,which combined with the idea of whole life cycle design and added the knowledge of manufacturing,operation,environment as the constraints to the drive.The progressive driven strategy included index driven,navigation driven and template driven was created based on Product Life cycle Knowledge (PLK),which  achieved the integrated rapid design from user requirements to design scheme,structural model and simulation analysis.Key technologies in the realization process were further researched.The feasibility and effectiveness of the proposed method was verified by the design of large environmental protection equipment bag filter's tubesheet.

Key words: knowledge-driven, product design, product life cycle knowledge, driven strategy
