数字孪生车间以数字孪生技术为核心,能有效解决车间内物理空间与信息空间融合的瓶颈。阐述了当前复杂产品装配过程的特点,提出了实作装配体模型的概念,以及包括物理实体层、模型数据层、迭代分析层、协同服务层的复杂产品装配数字孪生车间的整体框架,研究了以装配体修正模型为核心的装配过程调控方法和数字孪生装配车间的运行机制。在此基础上分析了数字孪生车间对装配过程效能提升的促进作用,为复杂产品装配车间的改进提供了新的思路。

Study on Application of Digital Twin Workshop in Assembly Process of Complex Products

The digital twin workshop(DTW)uses digital twin technology as the core,which could effectively solve the bottleneck of the physical-cyberspace fusion in workshop.The characteristics of the current complex products assembly process are summarized,the concept of as-built assembly model,as well as the framework of the DTW for complex products assembly including physical entity layer,model data layer,iterative analysis layer,and collaborative service layer,are proposed.The regulating method of assembly process with assembly modified model as the core and the operation mechanism of assembly DTW are studied.On this basis,the contribution of the DTW to the efficiency promotion of the assembly process is analyzed,and a new idea for improving the complex products assembly workshop is provided.
