    Abstract
  • Macroscopic deviation of shaped charge is one of the reasons for lateral deviation of induced jet. In order to study the influence of multiple coupled macro deviations on the lateral deviation of jet, theoretical model considering the effects of the coaxiality deviation, the liner thickness deviation and the position deviation on the lateral deflection of the jet was deduced according to the jet forming theory. The numerical simulations of the jet forming process for the shaped charge containing multiple macroscopic deviations were carried out. The results show that the coaxiality deviation and the position deviation both cause the jet to form a quadratic curve, and the liner thickness deviation makes the jet deflect, but still maintain a straight shape. For the cases of multiple macroscopic deviations coupling, the lateral displacement of the jet is approximately the vector sum of the displacements caused by each single factor. The results provide a reference for improving the stability of shaped charge.
