Abstract

Due to the complicated, multi-hierarchy, multi-attribute and creative process of product structure configuration of complex mechanism scheme design, we study the extension design mode for adaptive design of a large complex product and propose an expression model of multi-type design knowledge in the process of product design. Combined with the field of knowledge and the related design constraints, the adaptive design of extension model is established. The objective function of extension adaptive design is to present the compatibility of the conditions and objectives in the process of adaptive design. Through establishing the ideal positive and negative domains, it acquires the weighted extension superiority of decision scheme. This paper puts forward the extension optimization method of adaptive design for complex mechanical products. Then, it establishes and proposes a framework of extension design model for complex mechanical products. Finally, it analyses the design of large hydraulic turbine products to verify the validity and operability of the model.
