摘要
While obtaining a Solution to the wheel-rail contact problem, a series of hypotheses are made in order to obtain a quick Solution. However, some of these hypotheses are not admissible when solving certain problems. Among these simplifications can be included the assumption of a constant friction coefficient and of it stationary state contact. In order to overcome these limitations. it new algorithm that takes into account the transient effects and it Falling friction coefficient is proposed in this work. This algorithm is based on FastSim, which has the best computational cost/precision ratio.
