基于数字孪生的设备加工过程监测技术研究

针对典型航空产品装配生产线的生产过程中缺乏有效的人机交互手段,设备实时运行状态可视化监控程度低等问题,提出了一种基于数字孪生的加工设备运行状态监测方法,包括模型构建与优化处理、NC程序解析与加工仿真、软硬件通信与数据传输和实时仿真与数据分析。最后在某航空发动机外涵机匣装配生产线验证了该方案,可以实现NC程序加工仿真分析、设备运行过程中状态的在线监测和实时三维仿真。

Research on Monitoring Technology of Equipment Processing Based on Digital Twin

Aiming at the lack of effective human-computer interaction methods and the low degree of visual monitoring of the real-time running status of the equipment in the production process of typical aviation product assembly production lines,a technical solution for operation status monitoring of processing equipment visualization and simulation analysis of processing equipment based on digital twin theory is proposed.The program includes model construction and optimization,NC program analysis and pre-processing simulation,software and hardware communication and data transmission,real-time data acquisition and simulation functions.Finally,it is verified on the assembly line of the aircraft engine external culvert assembly that the scheme can be used for NC program processing simulation analysis,online monitoring of equipment status during operation online monitoring of production line status information and real-time three-dimensional simulation.
