摘要:
基于玻璃钢游艇材料在被破坏时的模糊性，建立了模糊状态下玻璃钢游艇的可靠性模型，并计算了一艘玻璃钢游艇的总纵弯曲下的艇体结构可靠度.针对正态分布的结构极限方程和非正态分布的模糊变量，应用JC法计算结构经典可靠度；采用隶属度函数进行模糊可靠度的计算.最后，将计算的玻璃钢游艇总纵弯曲下的结构模糊可靠度结果与经典可靠度下的计算结果作对比，提出模糊可靠度的合理性及经典可靠度的保守性的结论.
Abstract:
In this paper a reliability model of glass fiber reinforced plastic yacht at fuzzy state was established based on the fuzziness of glass fiber reinforced plastic yacht when its material is destroyed,and the reliability of the hull structure with the total longitudinal bending was calculated.At first，the structure classical reliability was calculated using JC method,considering both the hull structural limit equation with normal distribution and the fuzzy variables with non-normal distribution.Secondly,the fuzzy reliability was calculated using the membership function method.It can be found that the fuzzy reliability is rational and the classical reliability is conservative through comparing the result of classical reliability with that of the fuzzy reliability for the glass fiber reinforced plastic yacht with total longitudinal bending.
