文摘 对EA4T型高速列车车轴钢棒状旋转弯曲疲劳试样实验段磨削加工后进行了表面超声滚压处理。观察了处理前后试样的表面形貌及表层微观组织,测量了处理前后试样的表面粗糙度、表层硬度及表层残余应力。利用旋转弯曲疲劳实验得到处理前后试样的疲劳极限。结果表明:表面超声滚压处理后,试样的疲劳极限由352MPa提高到401MPa。疲劳极限的提高主要由于表面超声滚压处理后试样表面粗糙度降低、表层强度及残余压应力增加。
其他语种文摘 The rotating bar bending fatigue testing specimens made from EA4T high speed axle were grinded. Some of the grinded specimens were surface ultrasonic rolling processed (SURP). The microstructures in surface layer and surface morphologies of the grinded specimens and the SURP specimens were observed. Micro-hardness and residual stress in surface layer and surface roughness of the grinded specimens and the SURP specimens were measured. Fatigue limits of the grinded specimens and the SURP specimens were tested using rotational bending testing method. The results show that fatigue limits of the grinded specimens and the SURP specimens are 352MPa and 401MPa respectively.The increase of fatigue limit of the SURP specimens is mainly due to the decrease of surface roughness and the increase of strength and residual compressive stress in surface layer.
