摘要
本文采用３Ｄ－ＦＥＭ方法对船舶整体结构进行振动分析。介绍了模型生成、附连水等处理方法。计算了２８．３万立方英尺、４５万立方英尺冷藏／集装箱船、２．１万吨多用途货船及３００ＴＥＵ集装箱船等多艘船舶，并和Ｇ．Ｌ计算资料和实船测量值作了比较，取得了较为满意的结果。
This paper presents the procedure for the vibration analysis of ship hulls using 3D finite element method.The model generation and the calculation of entrained water are introduced.283,000 c.f.refrigerated container ship, 450,000 c.f.refrigerated container ship,21000 DWT multipurpose cargo ship and 300 TEU container ship are dealt with as examples.The calculation results are compared with those of the G.L.calculation information and the full scale measurement value of the ships,showing their good coincidance.
