大型集装箱船扭转强度分析

Analysis of Torsional Strength in Large Container Ship

本文以２２０００吨集装箱船为实例，研究应用空间有限元模型计算船舶扭转强度的方法。根据集装箱船的特点，对实际船舶结构中的板，用板壳单元模拟，并计及波浪和货物引起的扭转力短，在边界条件处理时，剔除总纵弯曲的影响。用结构分析程序ＷＨＡＰＳ计算，所得结果准确可靠，从而找到了一种大开口船舶扭转强度分析的新方法。

Discusses the application of three-dimensional finite element model for the calculation of ship torsional strength hosed on an example of 22000dwt container ship. The plates of ship atructures are re garded as plate-shell elements in consideration of the container ship features,the torsional moments of wave and goods are considered,and the influence of longitudinal bending is ignored in treating boundary conditions. After calculation with the PCSAP5 program of strural analysis,the results are exact and reliable,so a new method is explored for analysis of chip torsional strength with large hatch openings.
