摘要：

锻造液压机是实现超大型零件快速锻造的重要装备。为了提升液压机锻造性能与可靠性，围绕数字孪生驱动的锻造液压机工作状态感知与虚实同步开展研究。通过分析锻造液压机工作状态实时感知与锻压风险预警的需求，构建了锻造液压机数字孪生框架，包含物理硬件层、感知控制层、孪生模型层和可视交互层。通过传感数据和仿真数据联合驱动液压机孪生体在线运行，基于孪生体实时仿真预警锻压风险，实现了锻压机锻造过程的可视化，提高了锻压机工作过程的可靠性，为锻造液压机生产过程数字孪生的实现提供了关键技术支撑。

Abstract:

The forging hydraulic press is an essential piece of equipment for achieving rapid forging of super large parts. To enhance the forging performance and reliability of hydraulic press forging, this paper focused on digital twin-driven forging hydraulic press working state perception and virtual reality synchronization. By analyzing the real-time perception demand of the hydraulic forging press’s working state and early warning of forging risks, a digital twin framework for forging hydraulic press was constructed, including a physical hardware layer, perception control layer, twin model layer, and visual interaction layer. The digital twin system of the forging hydraulic press was driven online by sensor data and simulation data, enabling early warning of forging risk through real-time simulation. This system visualized the forging process of the forging hydraulic press, improved the reliability of the working process of the forging press, and provided key technical support for the realization of digital twin in the production process of forging hydraulic presses.

Key words: digital twin, forging hydraulic press, state perception, virtual reality mirroring, 3D visualization
