Résumé

We present sufficient conditions for the existence of forced oscillations in nonautonomous mechanical systems. Previously, similar results have been obtained for systems with friction. The results presented here hold for systems both with and without friction. Some examples are given.

Détail

Keywords: forced oscillations, periodic solutions, inverted pendulum, geodesic, Nagumo condition, Ważewski method.
