Forced vibration derivation
WebForced Vibration. Forced vibration occurs when motion is sustained or driven by an applied periodic force in either damped or undamped systems. From: Plant … WebOne common cause of harmonic forced vibration in mechanical systems is rotating unbalance. This occurs when the axis of rotation does not pass through the centre of …
