Abstract

Aiming at the destructive influence of pulsed strong magnetic field on the guidance and control device in electromagnetic launching and the lack of repeated testing methods

an off-line testing method for the anti-magnetic field capability of the guidance and control device is proposed based on the analysis of the magnetic field characteristics. Comprehensive performance requirements of such as the magnetic induction intensity peaks

change rate and duration of the guidance and control device are given through analysis according to the actual working conditions of electromagnetic launches. Bases on system circuit analysis and magnetic field calculation modeling

a multi-objective optimi-ation design method is proposed

which takes into account the peak value and change rate of the magnetic induction intensity

the si-e of power supply and the magnetic field generator in working space. A finite element simulation is conducted to verify the design scheme. An off-line test device is final
