Abstract
The aim of this paper is to present the design of the twin-disc test rig for the study of the wheel-squeal phenomena. This test rig utilizes a dynamic model of the track-train interaction and uses real train wheel for a more realistic representation of the emitted noise. This twin-disc test rig is intended for research into the mechanisms of the wheel squeal noise formation and for the development and validation of a prediction model. In particular, the influence of weather conditions and the presence of various friction layers in the contact will be addressed.
