| 摘 要： | 针对内河船舶船体梁极限弯曲能力的计算与统计特性问题,将影响船体梁极限弯曲能力的主要因素作为随机变量,分别讨论了材料屈服强度与板厚的概率分布参数选取。采用增量迭代方法与改进Rosenblueth方法,计算得到船体梁极限弯曲能力及其分布参数。研究表明,极限弯曲能力计算时可不考虑板厚变异的影响,内河船舶船体梁极限弯曲能力具有统计上的稳定性。

| Abstract: | As to the calculation of hull girder ultimate bending capacity of inland navigation ships and its statistic characteristic, take the main factors which influence the hull girder ultimate bending capacity as random variables, and analyze the distribution parameters of yield strength of materials and thickness of plates. Calculate the hull girder ultimate bending capacity and its statistic characteristic using incremental iteration method and improved Rosenblueth method. It can indicate that the ultimate bending capacity can be calculated without considering the influence of variation of thickness of plates. The ultimate bending capacity of inland navigation ships has statistic stability. |
