【摘要】 本文依据船舶规范对动倾斜力矩与复原力矩的校核相关要求,以及船舶受海浪、横风等随机因素影响下,船舶的动倾斜力矩在不同的蒲氏风级的变化情况,提出了一种横稳性可靠性分析的建模方法,同时建立横稳性可靠性的估算流程,通过一次二阶矩法计算出在不同蒲氏风级下的横稳性可靠性,并获得船舶在不同蒲氏风级下安全系数与随风级变化的可靠性指标。更多还原

【Abstract】 According to ship specification of dynamic tilting moment and restoring moment checking on related requirements,and the ship by waves,wind and other random factors affecting the ship dynamic tilting moment in the different PuShi wind scale changes,this paper proposed a modeling method of transverse stability reliability analysis,at the same time,establish the reliability of the transverse stability estimating process through First-order Reliability Method calculated in different PuShi and to get the ship in a different safety factor and reliability index level changes with the wind.更多还原
