数字孪生及其质量管理方法思考

Digital twin and thinking over its quality management methods

数字孪生作为工业界和学术界关注的战略性技术之一,可视为连接数字空间与物理空间的桥梁,通过多维度动态模型、实时监测及反馈系统、动态环境模拟更新等方法,可以在数字空间实现对物理空间的描述与预测,从而指导更优的决策。介绍了数字孪生诞生的背景及发展历程,梳理了国内外数字孪生技术研究现状,阐述了数字孪生及相关概念的内涵,最后重点讨论了针对产品全生命周期数字孪生体,在方案设计、工程研制、设计定型、生产制造和使用维护阶段的质量管理控制方法。

As one of the strategic technologies concerned by industry and academia,digital twin can be regarded as a bridge connect⁃ing digital space and physical space.Through multi-dimensional dynamic models,real-time monitoring and feedback systems,and dy⁃namic environment simulation updating,we can realize the description and prediction of physical space in digital space,so as to guide bet⁃ter decision-making.This paper introduces the background and development history of the birth of the digital twin,combs through the sta⁃tus quo of digital twin technology research at home and abroad,explains the connotation of the digital twin and related concepts,and final⁃ly focuses on the discussion of the quality management and control methods for the digital twin of the whole life cycle of the product in the program design,engineering development,design and finalization,manufacturing,and use and maintenance phases.
