Research on Construction Method of Digital Twin Workshop Based on Digital Twin Engine

The concept of the virtual workshop has been proposed for many years, and many companies have built their own virtual workshops for planning and simulation. But only virtual workshop cannot realize the interaction of the physical world and virtual world required for smart manufacturing. The digital twin workshop is a useful way to realize the fusion of virtual workshop and physical workshop, and optimizes the activities. This paper studies the concept of digital twin workshop, and digital twin workshop is divided into three parts: virtual workshop, physical workshop and digital twin engine. At the same time, this paper emphatically analyzes the definition and function of the digital twin engine in the digital twin workshop system, and also proposes an architecture for building the digital twin workshop based on the virtual workshop models. Finally, taking the implementation of digital twin workshop of an intelligent manufacturing unit as an example, the effectiveness and functionality of the digital twin workshop of an intelligent manufacturing unit are verified based on the digital twin engine.
