Parameters Optimization of Passive Electromagnetic Armor Based on Orthogonal Experiment

In order to improve the defense ability of the passive electromagnetic armor (PEA), the parameters of the armor are optimized based on the orthogonal experiment. It analyzed the working principle of the PEA and the phase change of metal jet, and then the temperature control equation of the metal jet was obtained. After that the capacitance C, the charge voltage U and the distance of armor plates d were optimized based on the orthogonal experiment and the numerical simulation method of temperature field. At last, a group of optimized parameters were obtained. It can draw the conclusion from the research that the temperature distribution of the metal jet is not even, and the external surface of the metal jet has the highest temperature, as the internal side has the lowest temperature. Meanwhile, the charge voltage U has the greatest effect on the temperature of metal jet, and the capacitance C has the least effect. The research results are very important to the design and the application of PEA.
