| Abstract |
We consider a system that consists of a supporting rigid body and
two-degree-of-freedom gyros and is not a gyrostat in general. The equations
of motion of the system under the action of arbitrary forces are derived.
The case in which external couples are absent and only dissipative and
potential torques act in the gimbal axes is considered. We show that the
limit motions of the system are equilibrium motions in which the gyro
gimbals do not move relative to the support. Differential equations for
equilibrium motions and algebraic equations for steady motions are
obtained. We find an auxiliary function V (the total energy calculated
for "frozen" rotors) that does not increase along motions of the system
and prove a theorem on the correspondence between steady motions and
stationary points of V on the manifold determined by the angular momentum
integral of the system. We discuss a method for stability analysis of
steady motions in which V is used as a Lyapunov function.
The results are generalized to the problem on the motion of a system of
rigid bodies connected by hinged joints. |
