摘要
论文分析了强度和应力均服从正态分布的某壳体结构的强度可靠性。首先对壳体建模,然后分析计算出其最大应力和平均应力。应用了可靠性理论对壳体强度进行了可靠性分析,分析了安全系数和变异系数对可靠度指标的影响规律。
In this paper ,a strength reliability analysis of the structural model whose strength and stress are all normal variables ,is presented .The average stress and the max stress are established after structural model building .The strength reliability analysis of the lamella is established ,the influence of the safe coefficient and the variance coefficient to the reliabili‐ty are analyzed .
