Test results show 1 the fatigue strength of peened joints under overloading, in spite of lower than the fatigue strength of the non-overloading peened joints, is still greatly higher than the fatigue strength of as-welded joints; 2 In the range of lower stress level and longer life, ultrasonic peening method exhibit better results than TIG dressing; 3 Fatigue strength of the welded joints with defects (such as undercut at the weld toe) can also be improved greatly after peening treatment.
结果表明，超声冲击处理过的焊接接头经过载后疲劳性能有所下降，但与原始焊态相比提高疲劳强度、延长疲劳寿命的效果仍然十分显著；在低中应力水平、中长寿命区域，使用超声冲击法提高焊接接头疲劳强度比TIG熔修法效果更好；超声冲击处理后，含咬边等缺陷的焊接接头，疲劳强度同样有较大的提高。

The contact fatigue strength was measured after the 20CrNi2Mo and 15CrNi6 steel used asdragging gear on quasi high speed locomotive was carburized and quenched as well as peened,com-pared with that of 20CrMnMo steel.The results shown that the contact fatigue strength limits of thesethree types of steel carburized and quenched essentially same,and the contact fatigue strength Iimit hasbeen increased by 5 porcent after peening,and that the failure appoarances of all contact fatiguespecimen were delamination ...
对20CRrNi2Mo、15CrNi6及20CrMnMo渗碳淬火齿轮及15CrNi6渗碳淬火＋喷丸处理齿轮进行了弯曲疲劳试验，介绍了齿轮试件的设计与加工、试验装置与夹具、试验方法及试验数据的统计处理，试验结果表明，20CrNi2Mo和15CrNi6渗碳淬火齿轮在R＝0.99时的σFlim分别为530MPa和375MPa，与20CrMnMo渗碳淬火齿轮相比，弯曲疲劳强度分别提高80％和27％。15CrNi6经渗碳淬火＋喷丸处理齿轮在R＝0.99时的σFlim为490MPa，比未喷丸处理者提高30％。

Spring fatigue strength is a key performance index. Fatigue strength is less than static stress strength such as elasticity limit,yield strength.
弹簧由于承受交变应力的作用，在运行过程中发生的弹簧断裂主要是疲劳断裂，所以，弹簧的疲劳强度是关键的性能指标。
