Abstract

To calculate a rudder system’s vibration characteristic, MSC Nastran was carried out to simulate an underwater model’s wet modes based on finite element method (FEM) and virtual mass method. The model was simplified from the rudder system using a torsion spring instead of the transmission parts. The frequencies and mode shapes of the system’s first 4 order wet modes were obtained and showed differences in comparison with the dry modes. It could be concluded that the water’s effect plays a significant role on rudder system’s structural dynamics which should not be neglected in its normal modes analysis.
