Argumentary oscillation phenomenon (working document)

1 Dynamique des structures et identification

When a Duffing oscillator with one degree of freedom is submitted to an external harmonic force whose frequency is much higher than that of the oscillator, it is possible, under certain conditions, that the motion of the oscillator, once launched, is maintained at a stable energy level. This may occur when the force exerts its action only when the oscillator is close to its center position.
