In transit research and attitude control (TRAAC) satellite design rigid body in circular orbit was stabilized by gravity gradient forces and damped by lossy spring (dumbbell) connected to satellite body; new damping concept is presented in which two linearly uncoupled normal modes of vibration are damped by single linear rate damper acting on one of modes; coupling between modes is provided by nonlinear terms of second order, which for 2 to 1 ratio of modal frequencies lead to resonant exchanges of modal energy; damping force must act directly upon higher-frequency mode; concept is applied to satellite attitude-stabilization system, where it improves damping; numerical studies are made using method of averaging to obtain envelope response of motions.
