Abstract

This paper presents the results obtained from numerical simulations carried out with two-dimensional finite element models, developed to evaluate the behavior of the typical materials that constitute the support of railway sleeper systems of urban trains. Several loads to which this type of system is subjected and other factors such as the speed at which they operate are considered. Likewise, the substitution of some of the elements is evaluated to improve the performance of the system. The results obtained are compared with those obtained with some of the empirical equations most used in practical engineering to know the level of variability involved in using them.
