RESONANT MECHANICAL MOMENT DURING ROTATION OF A MICROSATELLITE WITH A MAGNET AND FLYWHEELS ON BOARD: FEATURES, TIME INTERVAL, MEASUREMENT METHODS

摘要

We consider the problem of ensuring predetermined attitude of a microsatellite with three flywheels and a strong permanent magnet with hysteresis rods on board. Small displacement vector of magnetic moment of the magnet models the perturbing effect of various equipment installed on board the microsatellite. Application of the integral manifolds method and the averaging method allow us to obtain the mechanical torque induced by the main resonance. The aim of the present research is to study the new small mechanical torque caused by the resonance, resulting in a significant microsatellite angular speed evolution of motion of non-resonance areas adjacent to this resonance. The main problems discussed in the paper are initiation of the torque, its specific features and scope as well the methods used to measure the induced resonant torque.
