Traditional design,manufacturing and maintenance are run and managed independently under their own rules and regulations in an increasingly time-and-cost ineffective manner.A unified platform for efficient and intelligent design-manufacturing-maintenance of mechanical equipment and systems is highly needed in this rapidly digitized world.In this work,the definition of digital twin and its research progress and associated challenges in the design,manufactur-ing and maintenance of engineering components and equipment were thoroughly reviewed.It is indicated that digi-tal twin concept and associated technology provide a feasible solution for the integration of design-manufacturing-maintenance as it has behaved in the entire lifecycle of products.For this aim,a framework for information-physical combination,in which a more accurate design,a defect-free manufacturing,a more intelligent maintenance,and a more advanced sensing technology,is prospected.
