摘要：
Electromagnetic forming technology is an advanced manufacturing technology that uses Lorentz force to drive high-speed deformation of metal materials. Compared with the traditional static forming process, electromagnetic forming can significantly improve the forming performance of light alloy materials due to its extremely high strain rate. At the same time, compared with the traditional mechanical force or hydraulic pressure, the Lorentz force used in electromagnetic forming can be flexibly adjusted in time and space, so it has richer process potential. However, the existing research mostly focuses on the forming method and effect of metal workpieces, and the most important part, the Lorentz force and the complex competitive relationship have not been systematically analyzed. Therefore, this paper focuses on the typical single-pulse electromagnetic forming process, refines the dynamic relationship between the various physical quantities in the electromagnetic forming process, and studies the competitive relationship of the time-varying Lorentz force on the aluminum alloy plate during the forming process and its influence on the forming process. The competitive relationship of the Lorentz force that changes with time is clarified, the influence on the forming effect is analyzed, and the electromagnetic forming technology process can be comprehensively understood. © 2022 Chinese Machine Press.
