● ABSTRACT:
The possibility to suppress the vibrations of a free gyro by an auxilary mass,
attached to the rotor by an axisymmetrical mount which consists of spring and damper,
is investigated. The mass and flexible mount rorate with the rotor. The mass has
two-degree-of-freedom, relative translational displacements. In the first part an
approximate model is considered assuming the gyro motion to be a forced moving base
for the mass. In the second part the general case and the conditions for stability
are considered. As a result the rotor has to be flat and the mass has to be
subcritical.
