Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2015-08-30 Abstract This work investigates the energy dissipation in a wheel/rail system through friction work modeling. In order to identify the effect of the friction coefficient on the energy dissipation in the wheel/rail contact, several simulations were performed using a 3D multibody model of a railway vehicle implemented in the software package VI-Rail Adams, with a friction coefficient varying from 0.2 to 0.7.The energy dissipation and wear rates of the inner and outer wheels of the first bogie of the vehicle running over a curve of a metro line were calculated for different friction coefficients. The total frictional work was obtained from the resultant force and slip in a reference point. The wear was also analyzed according to the T? method including the spin, in combination with Kalker’s simplified theory Fastsim, assuming that the wear is proportional to the frictional work. Two sets of rail and wheel profiles were studied in order to determine the effect of the profile’s quality on the energy dissipation and wear rates. To such an end simulations and energy calculations were performed with a friction coefficient of 0.4 Subject multi-body simulationenergy dissipationfrictional workwearWheel and Rail Profiles Quality To reference this document use: http://resolver.tudelft.nl/uuid:f78ebff2-89e3-4e40-8963-3cdccca2af90 Source CM 2015: 10th International Conference on Contact Mechanics and Wear of Rail/Wheel Systems, Colorado Springs, USA, 30 August- 3 september 2015 Part of collection Institutional Repository Document type conference paper Rights (c) 2015 The Author(s) Files PDF 326071.pdf 873.82 KB Close viewer /islandora/object/uuid:f78ebff2-89e3-4e40-8963-3cdccca2af90/datastream/OBJ/view
