Abstract

Effective pinch effect time of coil magnetic field on shaped charge jet is very important for test design and engineering application of High-Explosive Anti-Tank(HEAT) electromagnetic enhancement. The effect characteristics and effective pinch effect time of coil magnetic field on shaped charge jet are analyzed with theoretical analysis and finite element simulation calculation. The results showed that, electromagnetic force of the protuberance of shaped charge jet is bigger than that of the pit at the same time. Time is between 3µs and 6. 5µs, which makes shaped charge jet to generate effective deform with magnetic field of coil when the frequency of pulse current is 50kHz, it can produce large enough magnetic pressure difference, and make shaped charge jet to generate effective deform.

Key words： magnetic field of magnet exciting coil; shaped charge jet of HEAT; effective pinch effect time; electromagnetic force; magnetic pressure difference
