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.
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%。
Experiments show that Self-Piercing Riveting (SPR) is better than spot welding with regard to static strength and fatigue strength for aluminum alloys joining, SPR has a prominent application.
试验证明，自冲铆接工艺在连接铝合金时，无论是抗静拉力和抗疲劳性都要好于点焊工艺，因此，自冲铆接机在车身轻量化制造中有很好的应用前景。
