| Abstract: | In this paper the special welding stimulation analysis software(SYSWELD) has been used to analyze the welding joint on vice bogie frame.The X-ray diffraction method(XRD) has been applied into the measurement of residual stress produced on the vice bogie frame before and after vibration.The welding technologies and the vibrational stress relief methods have been verificated by XRD,which lay a foundation for the security reliability of the welding joint on vice bogie frame.The research shows that the results of finite element and XRD are in good accordance with each other.By formulating reasonable welding technologies and implementing vibration,residual stresses produced on vice bogie frame can be reduced in terms of security reliability. |
