| Abstract: | The dynamic force of the crossing bar of the K6 Bogie used in the 20,000 ton heavy-duty train in Da-Qin Railroad is identified in two methods:the material mechanic method and the quasi-static method.In addition,the axial force spectrum,transverse force spectrum and vertical force spectrum are worked out.Lastlys comparisons of the maximum and minimum of the identified force used in the two methods and the error analysis are carried out. |
