| Abstract: | Three-dimensional finite element model for a 58.5m Wave Piercing Catamarans(WPC) is firstly established in this paper.And then global and local vibration analyses ares carried out using the model.Complex vibration characteristics of the WPC,including torsional,vertical,horizontal vibration and their couples,are obtained from the analyses,which are different from the conventional ships.Finally,prevention vibration measures for the current WPC are briefly discussed. |
