摘要
现代远洋渔船结构在设计时通常采用确定性法,未能完善的考虑突发性、偶然性因素的影响,采用可靠性方法分析能够更好的反应结构力学的性能.本文针对一艘远洋渔船,考虑其满载状态,建立失效模式,分析了随机变量,并应用可靠性的中心点法进行分析,结果表明满载状态下船体总纵强度具备良好的可靠性,且屈服强度是影响可靠性较大的参数.
The deterministic method is usually used in the design of modern ocean-going fishing vessel structures,which fails to take into account the impact of sudden and accidental factors. The reliability method can better reflect the mechanical performance of structures. In this paper,considering the full-load state of an ocean-going fishing vessel,the failure mode is established,the random variables are analyzed,and the central point method of reliability is used to analyze. The results show that the overall longitudinal strength of the vessel under full-load state has good reliability,and the yield strength is a parameter influencing the reliability.
