Abstract
Electromagnetic loading liner is a new way to obtain a jet, which utilizes the Lorentz force to collapse the liner. To form effective jet, the jet critical forming model of electromagnetic loading is established based on the traditional jet critical forming conditions and electromagnetic loading characteristics. Through dimensional analysis, control variable method and theoretical calculation, the upper and lower critical peak current distributions are obtained. Finally, the loading current of 1mm thick liner structure is optimized by the critical peak current distribution diagram. The jet forming of the liner under the optimized current loading is calculated through theoretical simulation. The whole liner forms a jet, and the jet velocity, kinetic energy and liner utilization are much improved, which verifies the reliability of the critical current distribution diagram.
