Abstract:

Digital twin technology creates a virtual model of the object in a digital way, simulates the behavior of the object in reality based on the data, and achieves the purpose of shortening the product development cycle and reducing the cost by means of virtual and real feedback, data fusion analysis, and decision iteration optimization. There are many problems in the mechanical process system, such as poor real-time and interactivity of machining process monitoring, difficulty in diagnosing equipment faults, and large influence of machining errors. Digital twin technology is an effective way to solve these problems. This paper expounds the basic concept of digital twin and the technical route of mechanical process system driven by digital twin. The key technologies of virtual-real interaction system, multi-model fusion, algorithm prediction and intelligent decision-making based on digital twin technology are summarized. The specific applications of digital twin-driven mechanical process systems in each stage of the product lifecycle: product design, product manufacturing and product service, are summarized, and the functions of scheme formulation, process monitoring, process parameter optimization, equipment predictive maintenance and process evaluation of machined parts are realized. The opportunities and challenges brought by emerging enabling technologies for mechanical process system driven by digital twin are discussed. The future development trend is prospected from three aspects: key technology, application direction and data utilization, in order to provide reference for subsequent research.
