摘要
将整个船体简化为在纵向轴面内的平面模型，将上、下船体和连接柱简化为杆结构，用ABAQUS5有限元程序对双层油轮在不同波浪周期和波相条件下的受力情况进行计算和分析，得到连接柱上由波浪力作用产生的动态应力变化规律，确定了承受最大动态力的连接柱位置，并计算出每米波高对连接柱产生的最大动态载荷。为深入分析提供了有益方法，从而也为进一步改进和完善现有设计方案提供了根据。
By simplifying the tandem hull as a plane model on its longitudinal section, and the upper hull, lower hull and connectors as poles, and by means of the finite element program ABAQUS 5, the force on the tandem hull in different wave periods and under different wave phase conditions is calculated and analyzed, the regularity of variation of the dynamic stress on the connectors under the action of the wave force is obtained, the cormeetor receiving the maximum dynamic force is detennined, and the maximum dynamic load on the connectors produced by the wave of every meter height is calculated.
