| 摘 要： | 研究了截除低载对全机结构各部位裂纹扩展寿命的影响，导出寿命误差与裂纹扩展比的关系，并指出寿命误差主要取决于开裂结构的材料参数，而开裂部位的影响则可忽略不计。 |
| 关 键 词： | 断裂 载荷谱 截除 裂纹扩展 |

| Abstract: | The effect of truncation of lower loads in load spectrum on crack growth lives of overall structure points is investigated. The relation between life error and crack growth ratio is derived and analysis shows that life error mainly depends on material parameters of cracked structure and the effect of cracked location could be neglected. |
| Keywords: | fracture load spectrum truncation crack growth |
