| 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/伤容限分析的可靠度具有重要意义. |
| 关 键 词： | 比较损伤 分布 正态 对数正态 威布尔 |

| Abstract: | 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. |
| Keywords: | compared damage distribution normal lognormal weibull |
