Experimental and Theoretical Investigation of Railway Wheel Squeal

The authors note that their paper offers new results from a project designed to develop a complete, validated model of curve squeal noise generation. The model accounts for friction characteristics and excitation caused by unstable forces between the wheel and rail, along with vehicle dynamic behavior. Also included in this model are both wheel and track dynamic response and acoustic radiation. The paper details descriptions of the twin disc rig and the test methods. These test methods involve a modified twin disc rig used to provide experimental data for the validation of the model and measurement of the lateral force and dynamic response of rollers experiencing varying amounts of lateral creepage during squealing. The authors note that while there are extant theories to predict creep forces and their relationship to creepages, most have not been verified using empirical methods that characterize the falling friction coefficient observed during unsteady squealing. To address this, an outline of the squeal model is also presented. Tests results are compared with the prediction from the squeal model and with available theories. Good agreement is shown.
