| 摘 要： | 给出了一种由等幅载荷试验的断口金相数据反推得到的当量初始裂纹尺寸额定值（EIFSR）表征的紧固孔原始疲劳质量评定方法。并据此建立了原始疲劳质量符合性检查的EIF-SR判据和寿命判据。最后用上述判据对紧固孔细节进行了原始疲劳质量评定和符合性检查。

| Abstract: | An evaluation approach is presented to the initial fatigue quality of fastener holes, which is characterized by Equivalent Initial Flaw Size Rating (EIFSR) obtained by back extrapolated fractographic data of constant amplitude loading. Then EIFSR criterion and life criterion for initial fatigue quality evaluation and coincidence check are established. Finally, the initial fatigue quality of the fastener hole is evaluated and its coincidence is checked. |

| Keywords: | fastener holes initial fatigue quality equivalent initial flaw size rating coincidence check |
