A phenomenological equation of motion is proposed to account for two distinctive features of low-frequency inverted pendulums: frequency independent internal losses and instability at resonance frequencies below a critical threshold. The comparison with recent experimental data is discussed in detail. A new characterization of the background loss for a mass suspended as a pendulum by wires is also derived.

Abstract
A phenomenological equation of motion is proposed to account for two distinctive features of low-frequency inverted pendulums: frequency independent internal losses and instability at resonance frequencies below a critical threshold. The comparison with recent experimental data is discussed in detail. A new characterization of the background loss for a mass suspended as a pendulum by wires is also derived.File in questo prodotto:
