Abstract

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
