Análisis de lesiones en peatones producido en atropellamiento por vehículos, simulado en programa computacional de ingeniería asistida por computadora

Abstract

This research aimed to analyze injuries produced in pedestrians caused collisions in sedan-type vehicles. According to injury criteria established by the CEPE (United Nations Economic Commission for Europe) and EuroNCAP (The European New Car Assessment Programm). By using a computerized model of a manikin of Hybrid III crash tests. The behavior of the nodes of interest that exist in the manikin was carried out with the digitized 3D models and the element methods finite the vehicle selected for this analysis is the 2018 Hyundai Accent and modeled in SolidWorks. It was introduced common manufacturing materials in these types of vehicles, predominantly elastoplastic steel. The vehicle collision tests to the Hybrid III were developed with three speeds, up to a maximum of 50 km / h. The Hybrid III pedestrian standing version was reviewed in lateral position concerning the front of the vehicle. The mentioned parameters and the required for the simulation were introduced in the well-known control charts contained in the program LS-PRE POST. The results were obtained according to the data used in the control charts and were carried out the post-processing in the LS- DYNA program, with the data established from both CEPE as EuroNCAP and comparing them with the data obtained in the simulation. It was analyzed whether the collisions cause minor, serious injury, or even death to the pedestrian. As a gathered conclusion it is possible to regulate the maximum speed allowed to circulate this type of vehicle in urban areas. As well as intervening in the analysis of the materials that make up the vehicle. It is recommended to carry out new simulations with specific parameters such as the speed of the vehicle or manikin position to compare results.
