Abstract: The fault samples for railway freight rolling bearings are usually difficult to obtain in practice.A modeling method for rolling bearings is presented based on Pro /E and ADAMS.The acting forces are analyzed among different elements of railway freight rolling bearings,and the model for railway freight rolling bearings is built by using software Pro /E.The model for bearings is imported into ADAMS to add constraint,contact and driving forces by adding refer-ence axis.By using rigid -flexible construction,the outer ring is set as flexile body,while other elements are taken as rigid body.The experimental result shows that the vibration characteristic of model is consistent with theoretical situa-tion.
