Interference Simulation Analysis of Electromagnetic Induction Setting of Rocket Fuze

The electromagnetic induction setting technology is one of the primary methods of fuze wireless setting,which is a mature technology in engineering at present,but its theory research is still in its infancy.The theory of the electromagnetic induction setting is very important for achieving information transfer between fuzes and projectile firing system of tubular weapons.The primary coil is winded on the fired canister and the secondary coil is in the fuze,both form an electromagnetic coupled loop at rocket information setting,the fire control information is transformed to the fuze through electromagnetic induction method in time,then the fuze circuit obtains setting information after decoding analysis to achieve accurately control of the projectile.By using ANSYS the electromagnetic induction setting analysis model of rocket is established to discuss the influence of air gap and frequency to the setting effect.The interference problem among multi-tubular rockets is the emphasis to analysis,which will be a good instruction for the engineering design.
