“…Also it has to be mentioned the works of Telliskivi (2004) and Telliskivi and Olofsson (2004), where a semi-winkler based model is presented and applied to simulate wear on disc-on-disc and wheel-rail. Some of these mentioned models are summarized in De Arizon et al work (De Arizon et al, 2007). Finally, Hegadekatte et al (2008) have presented a simplified model (GIWM: Global Incremental Wear Model) which allow to estimate the maximum wear depth in pin on disc and twin discs tribometers, but not the solids profiles and contact pressures evolution.…”

a b s t r a c tThe present work shows a new numerical treatment for wear simulation on 3D contact and rolling-contact problems. This formulation is based on the boundary element method (BEM) for computing the elastic influence coefficients and on projection functions over the augmented Lagrangian for contact restrictions fulfillment. The constitutive equations of the potential contact zone are Signorini's contact conditions, Coulomb's law of friction and Holm-Archard's law of wear. The proposed methodology is applied to predict wear on different contact and rolling-contact problems. Results are validated with numerical solutions and semi-analytical models presented in the literature. The BEM considers only the degrees of freedom involved on these kind of problems (those on the solids surfaces), reducing the number of unknowns and obtaining a very good approximation on contact tractions using a low number of elements. Together with the formulation, an acceleration strategy is presented allowing to reduce the times of resolution.

“…Others recommend energy approaches, considering wear as an explicit function of the dissipated energy by friction in contact, such as Zobory's model [5,7]. This assumes that the contact area is divided into two zones: the adhesion and sliding zones and that the wear is highly dependent on sliding speed and therefore, the major part of the wear is located in the sliding zone of contact.…”

“…These variables are directly dependent on rail/wheel maintenance, in which the major concerns are wear and rolling contact fatigue, typically induced by friction and cyclic overstressing of the rail and wheel materials [1,2]. Some authors [3][4][5][6] suggest using Archard's wear model, which relates the proportionality of the wear volume with the sliding distance times normal force divided by the hardness of the material, Eq. (1), mainly because it is widely used and very accurate.…”

“…This assumes that the contact area is divided into two zones: the adhesion and sliding zones and that the wear is highly dependent on sliding speed and therefore, the major part of the wear is located in the sliding zone of contact. Another energy approach is Pearce and Sherratt's model [5,8], which is focused on the prediction of wheel flange and rail tread wear, estimating the wear loss as the area of the cross-section removed by distance covered (mm 2 /km).…”

“…In the literature, several approaches to estimate wheel and rail wear using dynamic simulations are available [1][2][3][4][5][6][7][8][9][10][11][12]. However, less emphasis has been placed on the consequences of that wear on the performance of the railway vehicles.…”

The search for fast, reliable and cost effective means of transport that presents better energy efficiency and less impact on the environment has resulted in renewed interest and rapid development in railway technology. To improve its efficiency and competitiveness, modern trains are required to travel faster, with high levels of safety and comfort and with reduced Life Cycle Costs (LCC). These increasing demands for vehicle requirements imposed by railway operators and infrastructure companies include maintaining the top operational speeds of trainsets during their life cycle, having low LCC and being track friendly. This is a key issue in vehicle design and in train operation since it has a significant impact on the safety and comfort of railway systems and on the maintenance costs of vehicles and infrastructures. The purpose of this work is to analyze how the wear progression on the wheelsets affects the dynamic behavior of railways vehicles and its interaction with the track. For this purpose a vehicle, assembled with new and worn wheels, is studied in realistic operation scenarios. The influence of the wheel profile wear on the vehicle dynamic response is assessed here based on several indicators used by the railway industry. The running stability of the railway vehicles is also emphasized in this study.
