摘要
空心轴的探伤直接决定着车轴的质量,对行车安全起着至关重要的作用,设计对CRH3型动车组心轴的探伤方法,通过分析探伤位、波形图像,提出判断裂纹形状的方法。为动车的空心轴探伤提供新的依据。
The crack detection of hollow shaft is a guarantee for the quality of shaft and plays an essential role for a safe operation of railway. This paper designs a crack detection method for the hollow shaft of CRH3 multiple units and brings forward a new way for determining cracks patters by analyzing detection zones and wave image, which can be regarded as a new basis for crack detection of hollow shaft for multiple units.
