Abstract：In order to improve the trouble-free operation rate of terminal operations, the digital twin technology is applied to the continuous ship unloader to map the physical entity and virtual space, which is conducive to the real-time monitoring of the working status of the continuous ship unloader, and intelligently diagnoses the possible operation problems of the continuous ship unloader. Therefore, under the theoretical background of the digital twin, the overall framework of the digital twin of the continuous ship unloader is established. The overall structure and working principle of the continuous ship unloader are analyzed. The finite element analysis software is used to establish the virtual mechanical model of the continuous ship unloader. A sensor installation plan for monitoring the dynamic variables during the working process of the continuous ship unloader is proposed. The realization method and technology of twin data transmission and storage, digital twin virtual and real mapping are introduced.
Key words：chain bucket continuous ship unloader；digital twin；finite element analysis
