English abstract:
We study the asymptotic behavior for a system consisting of a clamped flexible beam that carries a tip payload, which is attached to a non-linear damper and a nonlinear spring at its end. Characterizing the ω-limit sets of the trajectories, we give a suffcient condition under which the system is asymptotically stable. In the case when this condition is not satisfied, we show that the beam deflection approaches a non-decaying time-periodic solution.
Keywords:
Flexible beam, nonlinear spring, nonlinear damping, nonlinear semi-groups, trajectory precompactness, asymptotic stability.
