数字孪生在空间结构生命周期管理中的应用与挑战

Applications and challenge of digital twin in the lifecycle management of spatial structures

数字孪生是推动空间结构生命周期数字化、智能化管理的关键技术.为实现空间结构生命周期的智能管理,首先,分析数字孪生在“面向对象”和“面向过程”中的含义,给出基于数字孪生的空间结构生命周期管理新内涵;其次,分析空间结构在设计、建造和运维等结构生命周期管理各阶段的应用范式,以此建立数字孪生驱动的空间结构应用架构;最后,对数字孪生在空间结构生命周期管理应用中存在的挑战进行阐述和展望.研究表明,数字孪生是空间结构生命周期管理的技术保障,而高保真孪生体是实现数字孪生功能的重要前提.

Digital twin is the key technology to promote the lifecycle digitalization,intelligent management of long-span spatial structures.To achieve intelligent closed-loop management for the lifecycle of space structures,this paper firstly analyzed the meanings of"process-oriented"and"object-oriented"of digital twin and gave the connotation for the lifecycle-management of the digital twin-driven spatial structures.Secondly,on the basis of the application paradigms in typical scenarios of design,construction,operation,and maintenance of the lifecycle management of the spatial structures,this paper proposed the technical framework of digital twin-driven spatial structure.Finally,the existing challenges were discussed for the digital twin in the lifecycle management of space structures.The research shows that digital twin is the technical guarantee for the lifecycle management of spatial structures,and high-fidelity digital"twinning"is an important prerequisite for realizing the function of digital twin.
