Abstract
In this article, a multi-purpose platform for Hardware In the Loop (HIL) testing of safety relevant railway subsystems, such as odometry boards or wheel slide protection systems, is shown. The rig, called MI-6, is a product of the cooperation of Trenitalia with researchers of Dip. Energetica Sergio Stecco (University of Florence). In this work, special attention has been paid to vehicle real-time model optimization according to customer specifications (Trenitalia) and to simulate artificially degraded adhesion between rolling surfaces where conventional adhesion models have poor performances or require unaffordable computational resources for real-time applications. In this article, a heuristic model based on energetic considerations and a wide archive of experimental test (courtesy of Trenitalia Società per Azioni) is presented. Also some simulation results and comparison with the experimental data are shown.
