摘要
By studying shock wave propagation and fragment movement after the explosion of a blast fragmentation warhead,a whole calculation process about the place where fragments meet shock wave was proposed.A computing system for movement laws of fragments and shock wave was developed based on VC++.Numerical segment integration method is used for the calculation of shock wave velocity and displacement,which makes the calculation be more convenient.The movement of preformed fragments and shock wave was simulated by ANSYS/LS-DYNA.The results show that the simulation is nearly equal to calculation.
