Abstract: With the introduction of technologies and development strategies such as industry 4.0 and intelligent manufacturing,the research and application exploration in the field of digital twin has gradually become a research hotspot in recent years.Through the quantitative and visual bibliometric analysis method,the research results of the digital twins field was combed in WoS database,and the external characteristics of the literature in the digital twins field was analyzed by using the scientific metrology theory algorithm and visual analysis software.The research hotspots and hot spots evolution trend was discussed in the field,and the future research direction was put forward,which provided reference for the field scholars and enterprise practitioners who had pay attention to the field of digital twin provide.

Key words: digital twin, knowledge graph, visual analysis, research hotspot, field frontier
