| 摘 要： | 通过对SS8,SS9型机车用35CrMo车轴疲劳裂纹特点及小角度探头纵波探伤和斜探头横波探伤工艺方法的分析、试验,确定了35CrMo车轴中、大修时疲劳裂纹的超声波检测方法,保证机车轮对在不解体条件下,应力集中区疲劳裂纹能够完全检测出来,并能对裂纹深度范围做出初步判断。

| Abstract: | By analyzing characteristics of stress-centralized fatigue cracks in the 35CrMo axle using for SS8/SS9 electric locomotive and techniques of longitudinal wave non-destructive test with small angle probe and transverse wave non-destructive test with small skew probe,this paper ascertains the techniques of non-destructive test for the 35CrMo axle in secondary and heavy repair.Ensures that the stress-centralized fatigue cracks can be detected and the cracks depth scope can be elementary judged on the condition of the wheelset not being disassembled. |
