摘　　要：数字孪生技术被认为是实现信息物理系统的核心关键技术,作为数字孪生技术在产品研发过程具体应用的产品数字孪生体,目前其研究尚处于探索阶段,研究成果相对较少且缺乏系统性。为此首先回顾了数字孪生体的产生背景,在此基础上提出了数字孪生技术的概念,然后对产品数字孪生体的内涵进行了系统阐述,建立了产品数字孪生体的体系结构,并给出了产品数字孪生体在产品设计阶段、制造阶段和服务阶段的实施途径,最后指出了产品数字孪生体的发展趋势。Digital twin technology is considered as the core and crucial technology to fulfill cyber-physical systems. Product digital twin is one of applications of digital twin technology in the process of product development. Howev- er, the research on it is still in its infancy and there are only few unsystematic research findings presented. The con- cept of digital twin technology based on review of digital twin background and the architecture for product digital twin based on systematic analysis of its connotation were proposed. The implementation approach of product digital twin in the stage of product design, manufacturing and service was investigated. The evolving trends of product dig- ital twin concerning its features in the future were predicted.
