Análise de dinâmica longitudinal para um projeto conceitual de transmissão 4x4 aplicada em veículo mini Baja

Abstract

Due to the new regulations of the Baja SAE competitions, there arose the need for a 4x4 transmission project applied to mini baja vehicles. Therefore, the aim of this work is to develop a longitudinal dynamics study to define the construction parameters of the transmission system, aiming for the best performance and efficiency of the vehicle. This study considers the prototype in several track conditions, and the specification of the boundary conditions that had the most influence on performance for competition purposes. From the results of this analysis, we were able to determine the optimal transmission reduction ratio to make the most of the available tractive capacity. We also assessed the best constructive form of the assembly to meet performance needs and be economically viable, considering the utilization of components, costs, and available manufacturing processes. Conceptual modeling of the components was carried out to validate the proposed application of the project.
