Estudio paramétrico para dispositivos de cubrimiento y de cierre bajo norma NTE INEN-EN 124-1, 2019.

Abstract

The objective of the present work is to study parametrically, covering and closing devices for traffic areas used by pedestrians and vehicles under the NTE INEN-EN 124-1, 2019 standard and to analyze them by finite element method. The study of three physical parameters is carried out: mass, area and volume of commercial devices by the company FUNDIRECICLAR S.A. in order to optimize them and reduce their production costs, for which new geometries are designed by decreasing these parameters to study them with the pre and post-processing program for finite element analysis Autodesk Inventor Nastran, in which the boundary conditions are defined according to the work conditions of the element under analysis and standardized test procedures, thus obtaining strain and stress values, to later manufacture the new devices, and verify compliance with dimensional tolerances and weights. Finally, the validation of the prototypes manufactured in the testing laboratory of the Ecuadorian standardization service, INEN, is carried out and these results are compared (residual deflection, and behavior at full load) with those obtained in the simulation program, in this way, the regulatory design requirements are verified when evaluating the obtained results, concluding that by adequately modifying the geometry of the devices, their weight can be reduce and their mechanical properties can be preserved.
