The scope of this thesis is to make a structural analysis of the Daily vehicle and learn how to correlate the results with the homologation values in order to know if the vehicle would be ready to pass a homologative test. In order to understand this, first of all a brief description of the whole vehicle and their important points has been done, as well as a complete summary of the commercial vehicle most important regulations. The complete structural analysis has been done with numerical models provide by Iveco company, that allow us to focus the study in the parts that have a biggest interest for our results, in that way several configurations of each test have been designed in order to choose the better one. To perform the analysis the software package of Hyperworks has been used, which allow us to make a complete finite element analysis thanks to the pre-processor software Hypermesh or hypercrash to set the mesh and the initial conditions, the solver Radioss of which a complete and detailed explanation of how it works has been done and finally the post-processor to see the results with hyper view. With this entire package it have been possible to perform the analysis as we wanted, as well as report all the necessary data like accelerations, forces, energy… As for the results it will be possible to see a complete analysis and explanations of the performed test in order to achieve the normative. Also from each test, in order to understand the principal behavior of the most important parts, a detailed analysis with a numerical model has been done, in that way it helps to explain in a better way the results and allow us to make a complete correlation if we have it, with the real model. For some cases, it will be possible to see some modifications in the analysis or components, in order to focus the analysis in a more detailed part. At the end, it will be possible to now the most important normative in relation with the passive safety and the commercial vehicles, as well as to understand the used software and how a numerical analysis is performed to obtain the desiderate results, even more and one of the most important points, learn how each component work inside of the vehicle and for which reason have been thought in this way.
