摘　　要：本文以３５０００吨浅吃水型散货船为计算实例，建立各种型式的上层建筑有限元动力计算模型，并对此进行了动力计算分析，探讨了不同型式有限元动力模型之间的优缺点，研究了上层建筑和船体之间的耦合影响及其稳态强迫响应。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.
