Calculation and analysis of the scatter of load spectrum damage based on Fokker F27 airplanes

  • 摘要: 为考虑机群载荷谱分散性进行机群可靠性寿命评估,以56架Fokker F27飞机每次飞行的载荷因子-超越数曲线族为基础,编制得到56架飞机的载荷谱,选取SWT公式和线性累积损伤理论计算得到每架飞机的飞行载荷损伤、地-空-地载荷损伤和每次飞行载荷损伤,采用概率坐标回归方法进行拟合优度检验.结果表明,飞行载荷损伤服从威布尔分布、地-空-地载荷损伤服从对数正态分布,综合飞行载荷和地-空-地载荷损伤的每次飞行损伤服从对数正态分布,每次飞行损伤的对数标准差为0.073 7.
