摘　　要：为充分利用物理车间的实时数据,实现数据从物理车间精确映射到虚拟车间、驱动制造系统仿真与优化,提出面向生产性能数字孪生仿真的数据映射方法。从仿真数据建模、存储和更新3个方面分析了仿真数据与生产逻辑模型的融合过程;针对制造系统生产性能仿真需求,对原始生产现场样本数据进行了冗余分析、异常分析与剔除、统计与拟合等预处理;给出机器设备及在制品仿真数据的实时映射更新过程,驱动生产性能数字孪生的仿真运行、生产性能分析和优化。以制造车间为例,说明了该方法的应用过程,证实了仿真数据映射方法的可行性和有效性。To fully use the real-time data of the physical workshop to realize the accurate mapping of the data to the virtual workshop and drive the simulation and optimization of the manufacturing system, a data mapping method for the digital twin simulation of production performance is proposed. The fusion process of simulation data and production logic model is analyzed from the aspects of simulation data modeling, storage and updating. Focusing on the production performance simulation requirements, the redundancy analysis, outlier analysis and elimination, statistics and fitting of the original production site sample data is preprocessed. The real-time mapping update process of the simulation data of machine equipment and WIP is given in detail, and the simulation operation, production performance analysis and optimization of the digital twin of production performance are driven. The application process of the approach is showed by a case of a manufacturing workshop, which verifies the feasibility and effectiveness of the simulation data mapping method.
