hemispherical liner EFP warhead orthogonal optimization X-ray experiment
Using orthogonal optimizing design and numerical simulation methods,EFP warhead with hemispherical liner is optimized.The effects of EFP warhead structure parameters on the performance of EFP forming is analyzed.Ф65 mm caliber EFP warhead with variational-wall-thickness hemispherical liner is optimized.The velocity of optimized EFP is about 2.5 km/s and the ratio of length versus diameter of EFP is about 3.15.The numerical simulation shows the figure and velocity for EFP are similar to those of X ray experiments.
