The natural frequency of propeller shafting and bossing systems tends to become lower as propulsive horse power increases. In order to avoid resonance in the main propeller shafting, it is necessary to estimate resonance frequency accurately in early design stages. An analytical method based on a transfer matrix method was developed for three types of marine propeller shafting. In addition, full-scale measurement of lateral vibration was carried out for a 400,000 D.W.T. oil tanker and a 2-engine, 2-screw roll-on/roll-off ship. It was found that the present theory can be applied with satifaction when designing propeller shafting. It was especially noted that the characteristics of lateral vibration for different propeller blades are thereby clarified.
