VIBRATION EXCITATION FORCES FROM A CAVITATING PROPELLER. MODEL & FULL SCALE TESTS ON A HIGH SPEED CONTAINER SHIP

In connection with the technical trials with the triple screw container ship M/S Nihon measurements of pressure fluctuations and observations of propeller cavitation were carried out. In the present report the results thus obtained are compared with the corresponding results from tests in cavitation tunnel. The comparison also includes some results of theoretical calculations. The measurements of full scale vibration are analysed and compared with criteria of comfort. The results of the investigation are summarized at the end of the report. In an Appendix the different methods used for analysing the measurements of pressure fluctuations are described and compared.
