Stress Analysis of Interference Fit in Wheelset

Abstract:

The locomotive wheelset running with a high-speed, the wheels and axles of wheelset usually assembled by interference fit, the radial contact stress produced by interference cause the friction on the contact area, the axial force and torque of the wheelset transmitted by the friction. The value of prestress produced by the magnitude of interference change small in each load case, and it plays the main role in total stress of wheelset. So it’s very important that choosing a appropriate interference for the wheelset assembly base on the results solved by the finite element contact analysis.
