Abstract:

The report is the fourth in a series of engineering studies on railroad vehicle wheel performance. The results of saw cut tests performed on one new and one used wheel designed for a fleet of multiple unit (MU) power cars are summarized and analyzed. Reconstructed residual stresses are computed in the usual manner, namely: by modeling the deformed cut wheel with finite elements and prescribing displacements to close the cut. Similar cases are computed, with thermal stresses calculated from a companion finite element model to play the role of residual stresses, in order to simulate the experiment reconstruction analysis.
