In recent years, liquid dampers are widely used in spacecraft for damping angular vibra-
tions. Damping of the angular vibrations of gyroscopic systems by the use of a liquid
damper has so far not been studied sufficiently. In this case, in order to increase the effi-
ciency of the damper, it is necessary to optimize its parameters. In this article, we consid-
er the dynamic damping of forced oscillations of a uniaxial gyrostabilizer by a damper
with a toroidal cavity completely filled with a viscous liquid. An integro-differential
equation describing the oscillations of a gyroscopic system is obtained. A new approach
to optimizing the parameters of a liquid damper is proposed. The expression for the op-
timum coefficient of viscosity of a liquid is found. The results obtained can be used in the
design of a liquid damper not only in gyroscopic instrumentation, but also in other areas.
