Diseño y construcción de una jaula de seguridad para un vehículo de competición modalidad Rally

Abstract

This technical project was carried out in order to design and build a safety cage that complies with all the parameters described for safety structures in Article 253 of Annex J of the International Automobile Federation (FIA) Regulations and the Regulations of the Ecuadorian Automobile and Karting Federation (FEDAK). Different existing safety cage designs were investigated in order to obtain an adequate configuration of the structure and it was modeled using computer aided design (CAD) software based on the Hyundai Grand i10 vehicle model. A computer aided engineering (CAE) software was used for the simulation, where tests of loads applied on the structure were performed to measure its displacement in different directions, also frontal and lateral crash tests with a pole were performed to check if the structure mounted on the vehicle withstands these impacts without breaking any of its elements. The results of the simulations show that the safety cage complies with the ranges established in the FIA homologation regulations for safety cages and a good performance was obtained under normal operating conditions and in cases of impact.
