數字孿生通俗理解如下:
數字孿生是充分利用物理模型、傳感器更新、運行歷史等數據,集成多學科、多物理模友量、多尺度、多概率的仿真過程,在虛擬空間中完成映射,從而反映相對應的實體裝備的全生命周期過程。
拓展資料
數字孿生是一種超越現實的概念,可以被視為一個或多個重要的、彼此依賴的裝備系統的數字映射系統。
數字孿生是個普遍適應的理論技術體系,可以在眾多領域應用,目前在產品設計、產品制造、醫學分析、工程建設等領域應用較多。目前在國內應用比較深入的是工程建設領域,關注度比較高、研究比較熱的是智能制造領域。
數字孿生意義:比較為重要的啟發意義在于,它實現了現實物理系統向賽博空間數字化模型的反饋。這是一次工業領域中,逆向思維的壯舉。旦侍槐
人們試圖將物理世界發生的一切,塞回到數字空間中。只有帶有回路反饋的全生命跟蹤,才是真正的全生命周期概念。
這樣,就可以真正在全生命周期范圍內,保證數字與物理世界的協調一致。各種基于數字化模型進行的各類仿真、分析、數據積累、挖掘。
甚至人工智能的應用,都能確保它與現實談碰物理系統的適用性。這就是Digital twin對智能制造的意義所在。
