In this work the main results of a static and fatigue analysis performed by means of a computational model of a Tank-Car are presented. The tensile load (draft) is the more continuous condition presented during typical service situations, and is directly applied over the front draft lugs when the train starts its movement. In this sense, a three-dimensional finite element analysis of the wagon is carried out in the ANSYS Workbench platform. The static loads are applied in orden to estimate the fatigue life of the lugs. The material properties and boundary conditions were applied directly in accordance with the guidelines set out by the American Association of Railroads (AAR). The results of this analysis can be a useful tool for designers of railway equipment and to improve the designs safety.
