数字孪生通俗理解如下:
数字孪生是充分利用物理模型、传感器更新、运行历史等数据,集成多学科、多物理模友量、多尺度、多概率的仿真过程,在虚拟空间中完成映射,从而反映相对应的实体装备的全生命周期过程。
拓展资料
数字孪生是一种超越现实的概念,可以被视为一个或多个重要的、彼此依赖的装备系统的数字映射系统。
数字孪生是个普遍适应的理论技术体系,可以在众多领域应用,目前在产品设计、产品制造、医学分析、工程建设等领域应用较多。目前在国内应用比较深入的是工程建设领域,关注度比较高、研究比较热的是智能制造领域。
数字孪生意义:比较为重要的启发意义在于,它实现了现实物理系统向赛博空间数字化模型的反馈。这是一次工业领域中,逆向思维的壮举。旦侍槐
人们试图将物理世界发生的一切,塞回到数字空间中。只有带有回路反馈的全生命跟踪,才是真正的全生命周期概念。
这样,就可以真正在全生命周期范围内,保证数字与物理世界的协调一致。各种基于数字化模型进行的各类仿真、分析、数据积累、挖掘。
甚至人工智能的应用,都能确保它与现实谈碰物理系统的适用性。这就是Digital twin对智能制造的意义所在。
