摘要
利用在某型飞机载荷谱编制过程中提出的比较损伤计算方法,通过统计大量的外场飞参数据,分别按正态分布、对数正态分布和威布尔分布,研究了飞机在实际飞行使用过程中比较损伤的分布规律。研究结论对于飞机疲劳载荷谱的编制,提高结构疲劳试验,耐久性/损伤容限分析的可靠度具有重要意义。
The formula and mothed for compared damage are found during the period of compiling load-spectrum of a type of airplane. With the help of the large quantity of flight data, We research the distribution of the compared damage that was caused by flying, consist of normal, lognormal and weibull distribution.
