内河散货船总纵极限强度可靠性分析

摘要

According to various uncertainties affecting the structural safety of ships, the short-term and long-term forecasts for wave bending moment were calculated based on the 3D wave loads theory.The combination method of extreme external loads was chosen by Turkstra's principle.A suitable reliability analysis method including calculation of the failure probability in different operation conditions for inland waterway ships was proposed.A numerical example was given.%针对影响内河散货船船舶结构安全的不确定因素,采用三维势流水动力程序进行波浪弯矩的长、短期预报,根据Turkstra准则选择外载荷极值组合形式,提出适用于内河散货船总纵极限强度可靠性分析方法,对某内河散货船的不同工况进行计算和分析,给出不同工况下失效概率的计算方法.
