Grey Incidence Analysis on the Structure Parameters Optimization for Multiple Explosively Formed Penetrator

摘要

The study proposes a new method for optimization of the structure of Multiple Explosively Formed Projectile (MEFP) warhead. Firstly, the velocity of central penetrator and surrounding penetrator, divergence angle are chosen as optimization goals to establish a superior sequence function of typical parameters of shape charge and liner. Then grey incidence analysis and evaluation approach is employed to calculate the degrees of grey incidence, and the different weight coefficients to various optimization objectives for different structures of MEFP warhead can be obtained. Finally, a typical MEFP warhead is designed and tested to verify the optimization on performance parameters of MEFP in the experiment. Both simulation and experimental results show that the grey system theory can effectively guide the design and optimization of MEFP warhead.
