Abstract

A conventional pendulum has two equilibria, the lower one, and the upper one. This paper presents the stability problems of the upper equilibrium state in case of parametric excitation. We will show that the upper equilibrium can be stable due to the harmonic variation of the pendulum suspension point. By manufacturing the pendulum and the oscillator, we proved the theoretical results in practice.
