摘要: 本文从整个构件系统着眼,研究某型歼击机全动平尾转轴梁静强度的可靠性。具体采用Ditlevsen Bounds法计算其强度可靠度;用设计点线性化方法计算其扭转位移可靠度;并用Monte-Carlo数值模拟法计算最严重破坏模式的失效概率。

关键词: 元件破坏概率, 结构系统可靠度

Abstract: In this paper, the transmission shaft of the all-moving horizontal tail for a fighter plane is considered as a structural system, and its failure probability is analysed. The Ditlevesen Bound is used to obtain the strength reliability, and linear approximation at the designing point is used to obtain the torsion rigidity reliabib'ty.Finally, the Monte-Carlo method is used to get the reliability of the most serious failure mode for the shaft.

Key words: elementary failure pr}bability, structural system reliability
