Abstract:
The mathematical model of a six-axle 2TE25A diesel locomotive with asynchronous traction electric motors (TEM) is described, which includes the main mechanical components of the locomotive and their interconnections for predicting dynamic processes reflecting longitudinal, vertical vibrations, rocking of the body and bogies that occur in various modes during locomotive operation. The model takes into account non-stationary phenomena in the wheel–rail contact. Some results of modeling the dynamics of a six-axle section of a freight locomotive equipped with three-axle bogies with axial asynchronous TEMs are presented.
