Action Mechanism of Magnetic Field Enhancing the SCJ Stability

doi:10.3969/j.issn.1000-1093.2021.07.001

Abstract

Abstract: The craters penetrated by the the shaped charge jet (SCJ) coupling with the magnetic field are measured and analyzed to obtain the different stabilizing mechanisms of magnetic field enhancing SCJ stability at different stages. The characteristics of the craters penetrated by SCJ coupling with the magnetic field are analyzed through the static depth-of-penetration experiment and X-ray photograph, and then the coupling mechanisms of SCJ and magnetic field are researched based on the experimental results. The experimental results show that the coupling effect of magnetic field loaded at different timing could increase the SCJ stability under certain conditions, but the stabilization mechanisms are different, which mainly includes two aspects: the delayed breakage of continuous SCJ and the inhibited rotation of fractured jet particles.
