Abstract
<jats:p>This study focuses on the uniform pressure electromagnetic forming technology of hydrogen fuel cell titanium bipolar plates, focusing on the magnetic field distribution characteristics and its influence on the forming precision, and proposes corresponding control strategies. By establishing a three-dimensional finite element model, the magnetic field distribution under different process parameters is simulated and analyzed, revealing the mechanism of the effect of factors such as magnetic field intensity, frequency and pulse duration on the forming effect. The experimental results show that optimizing the magnetic field distribution can significantly improve the forming precision and uniformity of the bipolar plate. Based on this, an adaptive magnetic field control method is proposed in the study, which realizes the precise adjustment of the forming process through real-time monitoring and feedback control. This method effectively reduces the residual stress and improves the forming efficiency while ensuring the geometric accuracy of the bipolar plate. In addition, the study also explores the influence of titanium alloy material properties on the electromagnetic forming process, providing a theoretical basis for material selection and process optimization. The results of this study provide a new technical path for the high-precision and high-efficiency manufacturing of hydrogen fuel cell titanium bipolar plates, which is of great significance to promoting the development of the hydrogen energy industry.</jats:p>
