Digital twin acts as a crucial enabler integrating information space and physical world,in which the integration of complex product design-manufacturing is one of the key phases that facilities the application of intelligent manufacturing.However,current studies of digital twin technologies focus on the workshop operation and product maintenance,few efforts have been devoted to researching the capability of digital twin for the integration of complex product design-manufacturing.While there are various stages involved in realizing intelligent manufacturing,the most significant stage is the designing of the product,which is also the beginning of specifying digital twin as it impacts subsequent intelligent machining,assembly,operation and maintenance.Therefore,connation of complex product design-manufacturing integration based on digital twin was explored,and a ring-shape framework for digital twin-based complex product design and manufacturing was proposed.According to the framework,key techniques of digital twin-based complex product design and manufacturing were researched from the requirement,conceptual design,personalized configuration,virtual prototyping,multidisciplinary design,and data management perspectives.Two case studies were provided to exhibit application scenario of key digital twin techniques for complex product design and manufacturing integration.
