摘要
本文介绍了疲劳分散系数;并指出对于飞机疲劳寿命,在考虑分散系数时,应将两机翼看成是串联结构以确定其可靠度。文中还依据实验数据计算了AH-24飞机的延寿寿命。
This paper introduces the formulas of fatigue Life scatter factors and indicates that in determining reliability by means of scatter factors,the two wings of An-24 should be considered a series connection mechanism.In this paper,the lengthened service life of An-24 is also calculated according to the data of the test.
