NUMERICAL SIMULATION AND PARAMETRIC OPTIMIZATION OF ELECTRICALLY EXPLODING FOIL INITIATING SYSTEM (EFIS)

摘要

A physical model of EFIs firing process is set up in the present paper. It is applicable for the simulations of all kinds of EFIs. Parameters for firing circuit, electrical parameters, foil trip parameters and the thickness of flyer are optimized. The results show that there is a minimum value of energy to make exploding foil melting. The higher melting rate of foil is, the higher utilizating rate of energy is.
