Análisis de sistemas de protección frontal y posterior contra el empotramiento en colisiones de vehículos livianos con vehículos de categoría N2 para verificar el cumplimiento de las regulaciones N°58 y N°93 de la UNECE en la empresa Master Metal

Abstract

In the industry of vans for trucks, it was clear that the process of construction of the protective devices on the front and rear it is carried out in an empirical way, as there is no study on the resistance of these devices, there is a machine of impact to evaluate the resistance of the protective devices due to the high cost. This research is based on the simulation of the impact test on the front and back of the underrun protection systems manufactured by MasterMetal using a specialized software in finite element analysis, in order to determine whether the settings of the front underrun protection systems ensure the impact resistance during and after the test, as determined by the Regulations N°58 and N°93 (UNECE). The study found for the mechanical properties of the materials used in the manufacture of the protective devices, characterized in this way, the material, the validation of the results issued by the specialized software simulating the tensile test and comparing the results with those obtained from the physical testing. A modification was made in both protection devices demonstrating compliance with approval requirements described in the regulations N°58 and N°93 (UNECE).
