摘要
圆柱壳形构件是飞行器结构中常见的一种极其重要的结构形式,必须保证其具有足够的强度,刚度和稳定性,对其可靠性进行计算,具有重要的意义。本文采用基于验算点处展开泰勒级数的哈桑—林德法计算轴心压力作用下圆柱壳的可靠性指标。将均值点作为初始验算点,利用埃特金法计算可靠性指标,收敛速度快。
Cylindrical shell is an important and commonly-used part in the structural of aircraft,so the sufficient stiffness and stability should be guaranteed,and calculating the reliability of this part is significant.The Hasofer-lind method based on Taylor series expanded about design point is used to calculate the reliable index of cylindrical shell.The initial design point is regarded as mean value point.Aitken method is used to calculate the reliable index and speed up the convergence.
