NUMERICAL AND 3D SIMULATION OF ATBM CENTER CORE KE-ROD DISPERSION

摘要

With the numerical simulation, this paper studied the effect of parameter of rods circles, dispersion explosive and packing material of KE-rod warhead on the rod initial velocity, set up the formula to calculate the initial velocity of rod, based on modify Gurney formula. Experiments proved that this method could be help for engineering design. Meanwhile, with the VR method, the 3-D dispersion of KE-Rod is simulated.
