| 摘 要： | 对单长泥舱布置的挖泥船进行舱段破损强度分析。应用传统理论方法对船舶破损后的载荷进行计算,根据CCS的《钢质海船入级与建造规范》(2004)计算船舶两种工况的弯矩剪力,通过建立船舶舱段非线性有限元模型,计算舱段的极限强度。对以上三种计算结果进行比较分析,得出相关结论。

| Abstract: | The damaged longitudinal strength of dredges,which have a single mud holder,is studied.The loads of damaged hull are calculated by the traditional theories,and the bending moments and shear forces are obtained in light of the Rules and Regulations for Construction and Classification of Sea-going Steel Ships of CCS.Then the nonlinear finite element analysis is carried out to compute the ultimate strength of the hull.After comparing the numerical results,the authors draw out some conclusions. |
