摘要
分析一种船体腐蚀影响下随时间变化的船体结构可靠性计算方法.通过可靠性函数对船舶于规定运用期限内的不同时段的状况进行计算,并以一艘散货船为例,与传统的方法进行计算和比较,得出较为实时精确的结论.
A methodology to assess the time-variant reliability of the primary ship structure with hull girder degradation of corrosion is analyzed. The reliability function is calculated at discrete points during the ship＇ s life. A sample calculation is performed for the reliability of a bulk carrier comparing with the pres- ent practice and traditional one. And it is shown that, whenever degradation is present, the time dependent reliability calculated with the present practice shows more accurate dynamic result towards the end of the ship＇s life.
