摘要 通过改进的裂纹扩展分析程序对飞机关键部位进行相应载荷谱下的损伤容限分析和评定,依据关键部位模拟试件的损伤容限试验结果,确切给出该关键部位的损伤扩展能力评估并预测扩展寿命和剩余强度。全尺寸疲劳试验根据损伤容限评定结论进行了检查,保证了试验的成功,取得了良好的效果。 The damage tolerance analysis and assessment of the key component of the aircraft under the corresponding load spectrum was given by improved crack growth program.Based on the damage tolerance test results of the key component of the aircraft,the capacity of the damage growth was given exactly and the life of the crack growth and the residual strength were forecasted.The examination of the Full-scale fatigue test was given by the results of the damage tolerance assessment,which ensured the success of the test and achieved good results.
