VERIFICATION OF METHODS (FOR DETERMINING VIBRATION)

In this paper the correlation between measured and calculated hull and superstructure response is considered. Three different examples are presented, showing that the main resonant frequencies may be predicted with sufficient accuracy at the design stage. This makes it possible to select a proper propeller blade frequency and hence to reduce considerably the risk of unpleasant vibration. The problems of energy transport or effective excitation forces are discussed, and it is concluded that with the methods available at the moment, the calculated response will only give an indication of the global response level. Finally, some recommendations of further investigations into the problems of ship vibration are given and the present efforts of Det Norske Veritas in this field are outlined.
