Determinación de configuraciones estructurales de un frente de autobús interprovincial y su incidencia en la resistencia al impacto frontal mediante el método de elementos finitos

Abstract

The Research is based on the frontal impact simulation of the front section bus with the Finite Element Method for analyzing the resistance of different structural configurations and verify compliance with Regulation ECE R29. To simulate the geometry of the main components of an interprovincial bus involved in a frontal impact was made by allocating the material's mechanical properties and boundary conditions to recreate the closest to real event, then was determined that Structural Elements they are more affected during the crash in order to change their characteristics and create models that can be evaluated under the same test conditions. From the obtained models are validated and analyze numerical simulation results in order to find a structural configuration with which none of the components of the body intrudes driver survival space and comply with regulations UNECE R 29.
