Crash Analysis of a Pre-Engineered Electromobile Vehicle

Abstract

Although the need for fossil fuels, which is the energy source of internal combustion engines that are widely used in the transportation sector, increases continuously, the reserves are continuously decreasing. However, the fuel combustion reaction results in large damages to the environment due to effects of exhaust gas emissions. For these reasons, vehicles that work with alternative energy sources are being developed. In this context, the development of fully electric vehicles is being carried out today. In-wheel electric motor studies are one of the most fully electric vehicle developments. In scope of this study, frontal collision of a pre-engineered electromobile vehicle to straight rigid wall is examined via ANSYS Workbench LS-DYNA computer aided engineering (CAE) software. Since the analysis is a time-dependent dynamic analysis due to its structure, it has been performed by using explicit finite element method. The data of the acceleration, force and deflection values formed by collision effect on the head, chest and femur of the dummy were obtained by placing dummy into the vehicle model. The data obtained were compared with the critical limit values accepted by various authorities and the inferences were made regarding the injury status of dummy.
