Rail profiles have been measured on a real track and post-processed in order to be used in a mutlibody simulation of the train’s response. Wear modes have been extracted from the measures with a Principal Orthogonal Decomposition (POD). The profiles have been projected on these modes, giving a good characterization of the profiles’ geometry. In a second step, the train’s dynamic response on the measured track is simulated with a multibody software. The result shows that wear reduces the train’s stability.
