Kurzfassung englisch:
The author considers the planar rotational motion of
the mathematical pendulum with its pivot oscillating
both vertically and horizontally, so the trajectory of the
pivot is an ellipse close to a circle. The analysis is based
on the exact rotational solutions in the case of circular
pivot trajectory and zero gravity. The conditions for ex-
istence and stability of such solutions are derived. As-
suming that the amplitudes of excitations are not small
while the pivot trajectory has small ellipticity the ap-
proximate solutions are found both for high and small
linear damping. Comparison between approximate and
numerical solutions is made for different values of the
damping parameter.
