Abstract：High overload and strong magnetic field has become a typical characteristic of electromagnetic (EM) launch hypervelocity projectile, in order to break through the ability of resistance to high overload and strong magnetic of onboard devices, it is an urgent to research on simulation technology of the launch environment. In this paper, the high overload and strong magnetic field environment was simulated by the way of EM, and the simulation of an integrated test platform for high overload and strong magnetic field was also carry out. The analytical model of overload and magnetic field of this platform was established and the model correctness and platform output ability were validated by simulation. Simulation results show that it is feasible to generate high overload and strong magnetic field by the way of multistage EM coil. The platform can output overload whose peak is greater than 33 000g and whose duration time that value is greater than 20 000g can last more than 1.6ms. The platform can output magnetic field whose magnetic flux density (MFD) is greater than 7.0T and whose gradient of MFD is greater than 4 262T/s, and whose duration time that value is greater than 5T can last more than 10ms. The research results effectively make up for the defects that current simulation platform cannot meet the demands of overload and magnetic field of EM launch environment.
