摘要
Digital twin, as a technology of integrating multi-physics, multi-scale and multidisciplinary attributes, characterized by real-time synchronization, faithful mapping and high fidelity, could realize interaction and integration between physical space and virtual world. At present, digital twin had received great attention from academics and enterprises worldwide. With the advent of Digital Twin Shop-floor (DTS), digital twins were gained more and more attention on the potential of digital twin in smart manufacturing. The present situation of digital twin in enterprise application and theoretical research was discussed. Based on five-dimensional structure models of digital twin, six application principles were presented. On this basis, fourteen typical application of digital twin and their concepts and key scientific problems or technologies were explored. Which could provide theoretical and methodological reference for engineering practice of digital twin in the future.
