项目摘要

The ultimate strength of ship structures in the damaged as well as intact condition is studied including the uncertainty in the strength. The following achievements were made: (1) The ultimate strength of a continuous stiffened panel with crack damage under combined thrust and lateral pressure were investigated ; (2) The model uncertainty in the prediction of the ultimate longitudinal bending strength of a hull girder using Smith method was quantified ; (3) The Smith method was extended to be applied to the cross section with damages ; (4) ISUM system for the efficient analysis of the ultimate strength of a ship structure with and without damages were developed ; (5) A dynamical model to predict the collapse behavior of a ship hull girder considering the interaction between plastic deformation and fluid forcse was developed and verified by the tank test.
研究了损坏的船舶结构以及完整条件的最终强度,包括强度的不确定性。取得了以下成就:(1)在联合推力和侧向压力下进行裂纹损伤的连续僵硬面板的最终强度; (2)量化了使用史密斯方法预测船体梁的最终纵向弯曲强度的模型不确定性; (3)将史密斯方法扩展到具有损坏的横截面; (4)有和没有损坏的船舶结构的最终强度的有效分析的ISUM系统; (5)通过储罐测试开发并验证了一个动态模型,以预测船体梁梁的塌陷行为,并考虑了塑料变形与流体福克斯之间的相互作用。
