摘要
“数字孪生”是2002年提出的一个概念,它与系统工程越来越相关,更具体地说,与基于模型的系统工程(MBSE)越来越相关。数字孪生像虚拟原型一样,是物理系统的动态数字表示。然而,与虚拟原型不同的是,数字孪生模型是物理系统(孪生模型)的一个虚拟实例,在物理系统的整个生命周期中,它不断地更新物理系统的性能、维护和健康状态数据。
Digital twin is a concept put forward in 2002,which is more and more related to systemengineering,more specifically,model-based system engineering(MBSE).Digital twin,like virtual proto-type,is the dynamic digital representation of physical system.However,different from virtual prototype,digital twin model is a virtual instance of physical system(twin model).In the whole life cycle of physi-cal system,it constantly updates the performance,maintenance and health status data of physical sys-tem.This paper presents the general idea and basic principle of integrating digital twin technology into mbse.
