    Abstract
  • Numerical simulation with ANSYS/LS-DYNA software was accomplished on metal jet being disturbed by shearing movement of four-layer equivalent spaced plates. Disturbing performance of moving plates was analyzed according to jet rupturing forms, energy losing values, and the penetrating depth in target plate. The effects of the plates-velocity and the impact angle on the disturbing performance were obtained. The obtained results are as follow: the increasing of the plate velocity can improve the disturbing ability on jet; the disturbing efficiency was greater with the plates velocity beneath 100 m/s than over 100 m/s; and the disturbing extent can increase with the increase of the impact angle. All those results are significant for mechanical armoring research.
