| Abstract: | Usually,the superstructure and engine room of modern large-sized cargo vessel are arranged near the hull stern, and this kind of construction makes the vibration around this area more violent. In the present paper, a bulk carrier of 35000 DWT is taken as an example for calculation and the calculation results with five different FEM models are compared in respect to vibration performance of the superstructure additionally, merits and demerits are analysed for different kinds of models and studies are performed in relation to the coupled vibration between hull and superstructure. The stationary forced response of the superstructure under exciting forces caused by propeller and main engine is also examined. |
