Vibration Tests on Harbour Personnel Boat.

Abstract

Excessive propeller shaft bearing wear has occurred on a series of 10 metre harbour personnel boats constructed for the Royal Australian Navy. An investigation of the problem revealed that the wear was caused by a high-order whirling mode of the shaft excited by propeller-hull interaction. It was not practicable to alter this whirling vibration significantly, but the wear rate was reduced to an acceptable level by changing the bearing materials. (Author)
