The curve squeal noise by trams is a tonal noise of high amplitude produced by the wheel when negotiating sharp curves. A theoretical model to predict the noise and study the influence of different mechanical parameters in the generation of noise is presented. This first report describes the phenomena governing the squeal noise, presents the methods used to model it, and gives a kinematic study of the wheel sets, the bogie, and the rails motions.
