AN ANALYSIS OF BOW VIBRATION INDUCED BY ANTI-PITCHING FINS,

Abstract

A study was made of the exciting force, the pick-up mechanism, and the elimination of resultant system vibrations associated with the operation of anti-pitching fins on ships. The anti-pitching fin, when moving down during a pitching cycle, causes a ventilated bubble to be formed on its upper surface. It is the subsequent collapse of this bubble which gives rise to a sudden pressure impulse and is the exciting force. The pickup mechanism is the model's hull.
