Research by Simylation on Front-Rear Distance Influence of Following Warhead

To study the influence of the tandem warhead’s front charge to following warhead and verify the feasibility of installing annular shaped charge in the front of active missile’s warhead,the annular cutter’s influence to following warhead was simulated by ANSYS/LS-DYNA.The date of acceleration,velocity and displacement,the max stress of following warhead’s shell,charge and their place were obtained in different distance between front charge and following warhead.Simulation results showed when following warhead was relating rest to front charge,the shock wave of annular cutter affected following warhead’s acceleration,velocity,displacement and pressure of shell and charge,differently in different distance.
