So far, many studies have been published on the lateral vibration in marine shaft systems. These studies are, however, mainly on the critical speed of lateral vibration, and there are few total analysis on the responses caused by lateral vibration because evaluation of the factors (propeller exciting force, characteristics of shaft supporting systems, propeller damping, oil film damping of bearing, etc.) that have important effects on the responses is difficult.<BR>Today, with the tendency of the high-power shafting system, evaluation of the responses caused by the lateral vibration due to propeller exciting force is going to be required on the shafting design.<BR>Thereupon, the authors have made evaluation of the lateral vibration by utilizing the transfer matrix methods to meet the demand of shafting design. But, on the characteristics of propeller in these calculations, there are applied the conventional values.
