Description
Forging presses are key equipment for the high-precision forming of large forgings, and their hydraulic systems directly determine the loading capacity, motion accuracy, and forming stability of the equipment. To address the problems in the traditional design process of forging press hydraulic systems, such as reliance on engineering experience, data disconnection between CAD structural models and CAE simulation models, and the difficulty of quantitatively evaluating the dynamic response and performance influence caused by structural parameter changes at the design stage, this paper proposes a CAD/CAE integrated digital design and simulation verification method for forging press hydraulic systems. First, the structural composition and working mechanism of the forging press hydraulic system are analyzed, and parametric models of key components, including hydraulic cylinders, pumps, valves, accumulators, and pipelines, are established. Second, a cross-platform parameter-driven and automatic mapping mechanism between the design model and the simulation model is constructed, enabling the collaborative updating of geometric structural parameters, system configuration parameters, and simulation parameters. Furthermore, a digital simulation platform integrating parametric modeling, dynamic simulation, multi-source data import, result-curve analysis, and three-dimensional motion visualization is developed to analyze key indicators such as moving beam displacement, cylinder pressures, and valve opening states. The results show that the proposed method can integrate the design, simulation, and verification processes of forging press hydraulic systems, improve parameter iteration efficiency and simulation result traceability, and provide technical support for scheme optimization, virtual commissioning, and digital design of hydraulic systems in forging equipment.
