PREVENTION OF HARMFUL ENGINE-AND PROPELLER-INDUCED VIBRATIONS IN THE AFTERBODY OF SHIPS

A summing up of available procedures at DnV for prevention of harmful engine and propeller induced vibrations in the afterbody of ships. A design and control scheme is presented which may be used in time to fit in with the building schedule. Conventional propellers (single and twin screw) are shown to lend themselves to study by computerized methods now completed. Forced, damped shaft vibration calculations are briefly illustrated. Estimates of type and extent of propeller cavitation and corresponding hull pressure fluctuations complete the excitation loads required to perform forced vibratory response study of the hull structure components.
