| 摘 要： | 通过试验，研究了干涉配合铆接试件相对于普通铆接试件疲劳强度的增益，估算了冠状铆钉干涉配合的填充作用。研究结果表明：在中寿命区，干涉配合铆接的疲劳强度比普通铆接的疲劳强度提高约25％。通过理论计算与试验结果的对比。建议冠状铆钉干涉配合的填充系数可取为0．474。

| Abstract: | In this paper,the gain of fatigue strength of interference-fit riveting components compared with conventional riveting components is studied through tests, and the interference-fit filling effect of coronary rivet is estimated. Results show that in the middle life range the fatigue strength of interference-fit riveting increases by about 25% compared with that of conventional riveting. Based on the comparison between theoretical calculation and test results, this paper suggests that the filling coefficient of coronary rivet should be at 0.474. |
