Análisis estructural de una furgoneta de tipo M2 aplicando la carga dispuesta del Anexo 7 de CEPE R66 mediante análisis computacional

Abstract

The objective of this curricular integration work was to analyze the structure of a van type M2, applying the load provided in Annex 7 ECE R66 through computational analysis to evaluate the resistance of the body shell and the incidence in the safety zone of the passenger. This document presents a methodology for the simulation of vans rollover impacts. It was carried out a bibliographic review at baseline, with specific information of theoretical based on the study. The van structure was developed based on the general dimensions acquired from the catalogs and using CAD software. Four simulations were performed in CAE software taking into account the nonlinearity of the material and the necessary parameters. Two simulations of the impact of the pendulum regulation ECE R66 annex 7 and two simulations of the load exerted with the test simulations of the load exerted with the FMVSS216 test, to know the behavior when the load is varied. The values of energy, resultant displacement, strain distribution, and residual space criterion were compared in the simulation results through Hourglass energy. It concluded that the regulation ECE R66 annex 7 presents higher deformation values than the FMVSS-216 test, with a higher incidence in the survival space. The four simulations show a higher risk for passengers located in the front area, the rear frame of the structure presents higher resistance compared to the front part. Therefore, with the methodological procedure described in the document, it is recommended to carry out an individual study according to the regulation R66 annex 7, with other material properties or adding structural elements that present a higher resistance and do not invade the passenger safety zone.
