摘要:

将自制螺母喷丸前后的疲劳实验结果进行了对比，同时对比了喷丸后的自制螺母与同规格沈制螺母的疲劳实验结果。结果表明，喷丸强化可以提高螺母的疲劳寿命，喷丸强化后的自制螺母水平阶段的应力升降范围比未喷丸自制螺母明显上升，较大的静载荷比下，自制螺母断裂时的疲劳循环周次较低，喷丸强化后自制螺母的FLPF为24.38%，FSIP为26.26%，相同的喷丸条件下，自制螺母强化后的抗疲劳特性较同规格沈制螺母有显著提升，最大应力为160 MPa时，自制件的循环周次较沈制件提高了87.8%。

Abstract：

The fatigue performance of the home-made nuts of 1Cr11Ni2W2MoV steel before and after shot peening was comparatively studied, while taking the commercial Shen made-nuts as reference, the two kinds of nuts are made corresponding to the same national specifications. The test results verify that the shot peening can improve the fatigue life of the nut. The stress lifting range of the home-made nut after the shot peening treatment is much higher than that of the blank ones. Under an applied larger static load ratio, the fatigue cycle times of the blank home-made nuts is lower. After shot peening, the home-made nut has a fatigue strength increment percent of 24.38% and a fatigue life profit fraction of 26.26%. Under the same shot peening condition, the fatigue resistance of the home-made nut after shot peening is significantly improved compared with the Shen made-nut of the same specification. When the applied maximum stress is 160 MPa, the cycle times of the home-made parts is increased by 87.8% compared with the Shen made-counterparts.
