VIBRATORY PROPELLER FORCES ON ARBITRARY HULLS

An outstanding problem in regard to the design of ships is the selection of the propeller geometry and the location of the propeller in the aperture in order to reduce the sum of the propeller-induced vibratory bearing forces and moments and the hull surface forces and moments to an acceptable minimum. This paper presents a reliable method to predict these net excitations for quite arbitrary stern and propeller configurations. A computer solution for the propeller and hull excitations has been developed and assessed for its adequacy by comparisons with two sets of model measurements.
