Modelagem dinâmica e estrutural de um sistema de tração 4x4 aplicado para um veículo off-road tipo baja

Abstract

Due to recent changes in the administrative and technical regulations of the SAE Brazil Baja competitions (RATBSB), it became necessary to develop 4x4 traction systems to maintain the competitiveness of the prototypes that submit themselves to the annual competitions offered by SAE (Society of Automotive Engineers). In view of the need presented, this monograph aims to develop a quasi-static longitudinal dynamic modeling applied to a mini baja type vehicle in order to obtain the best power transmission ratio for the conditions imposed on vehicles in SAE Baja competitions. With the dynamic conditions previously analyzed, the structural dimensioning of the prototype's power transmission system will be done based on machine element concepts aiming at a safe and effective system to maximize power transmission to the four wheels of the prototype. In order to conclude the project, the assembly of the mechanical transmission set will be performed via CAD (Computer Aided Design) in order to enable the manufacture and assembly of the components previously dimensioned for the system.
