摘　　要：目前,很多制造企业构建了数字孪生工厂,用于工厂规划、仿真优化及实时监控,但是领域单一、周期短暂的数字孪生系统并不能完全体现制造企业实施智能制造所需的物理与信息世界交互共融理念。针对该问题,从制造企业数字孪生系统构建需求视角,提出制造企业数字孪生生态系统的概念、种群构成及内涵与特征。进而结合数字孪生技术的特点,研究了制造企业内数字孪生系统3个种群的构建过程与方法和3个种群之间的交互配置与动态演化过程。最后,结合某液压缸工厂智能化升级案例对所提出的制造企业数字孪生生态系统构建和演化进行了验证,证明了其能有效地提高制造企业的制造柔性和智能化程度,并能缩短产品研发周期,满足用户对高品质产品的个性化需求。Many manufacturing enterprises have built digital twin factory for factory planning,simulation optimization and real-time monitoring.However,the single-domain and short-period digital twin system does not fully meet the interaction and cointegration of the physical and information world required by manufacturing companies to implement smart manufacturing.To solve this problem,the concept,population composition and characteristics of the manufacturing enterprise digital twin ecosystem were proposed from the perspective of the construction needs of manufacturing enterprise digital twin system.Combined with digital twin technology,the construction process and method of three population digital twin systems in manufacturing enterprises and the interactive configuration and dynamic evolution process among the three populations were studied.The construction and evolution of the proposed digital twin ecosystem of the manufacturing enterprise was verified by combining the intelligent upgrade case of a hydraulic cylinder factory.It could effectively improve the manufacturing flexibility and intelligence of the manufacturing enterprise and shorten the product development cycle to meet the individual needs of users for high-quality products.
