MAGNETIC HYSTERESIS DAMPING OF SATELLITE ATTITUDE MOTION, VOLUME 1

Abstract

The attitude dynamics of a gravity-gradient oriented satellite, which employs soft nickel-iron rods as magnetic hysteresis dampers, is simulated by a digital computer program. A subroutine was generated to compute the flux induced in the rods for an arbitrary vehicle orientation relative to the earth's magnetic field vector. This subroutine was added to an existing computer program. Analytical expressions were fitted to empirical major and minor hysteresis loops, and a logic scheme was devised for tracing BH curves with an arbitrarily fluctuating applied magnetic field. This enables simulation of the effects due to the magnetic field encountered in orbit. Volume I of this report describes the analysis and the computer program in detail. Volume II presents the results of computer runs made under various initial conditions.
