航天发射场数字孪生技术初探

The Primary Exploration to Digital Twin Technology of Launching Site

针对航天发射场数字化建设和应用需求,结合国内外数字孪生技术发展提出了发射场数字孪生体的概念,详细阐述了其内涵、特性以及组成要素,初步建立了发射场数字孪生体的技术指导框架,形成了面向发射场全寿命周期的数字孪生体建设内容,设计了集三维设计模型、数字化合练系统、数字化试验系统以及数字化运维系统于一体的演进型数字孪生体,并对其应用模式进行了详细说明。相关研究成果可应用于我国航天发射场设计、建设、任务执行以及日常运维等工作。

A new concept of digital twin technology for launching site is proposed in this paper for the requirements of its digitalization and application.Based on the detail illustration of its intension,characteristics and composed elements,the fundamental technology framework is established for the digital twin of launching site.The work of building digital twin for the full life-cycle of launching site is also given,which consists of 3-dimension designed model,digitalized rehearsal system,digitalized test system and digitalized operation and maintenance system.In the end,the application modes for the evolved digital twin is introduced in detail.The research work described in this paper can be applied into design,construction,launching mission,daily operation and maintenance of launching site.
