面向生产线全生命周期的数字孪生模型应用

针对传统生产方式存在的管理成本大，生产效率低的问题，为实现智能化生产，设计了基于数字孪生技术的生产线全生命周期管理应用框架。首先基于物理生产线的多元数据，通过建模技术构建了生产线数字孪生模型，分别从生产线的规划阶段、调试阶段、运行阶段，为物理实体生产线提供仿真预演分析、连通调试、生产状态监控、数据可视化等服务。通过孪生模型对实际生产线的规划到运行阶段进行指导和改进，使企业生产线平衡率提高了6.84%,年产量增加了792件，结果表明该方法有效。

Application of digital twin model for the whole life cycle of production line

Aiming at the problems of high management cost and low production efficiency in traditional production methods, in order to realize intelligent production, the application framework of production line lifecycle management based on digital twinning technology is designed. First, based on the multiple data of physical production line, the digital twinning model of production line is built through modeling technology, including the planning stage, commissioning stage and operation stage of production line, provide simulation preview analysis, connection debugging, production status monitoring, data visualization and other services for the physical entity production line. The twin model was used to guide and improve the planning and operation of the actual production line. The balance rate of the production line increased by 6. 84% and the annual output increased by 792 pieces. The results showed that the method was effective.
