Desenvolvimento de um código em MATLAB para dimensionamento de uma caixa de direção de um veículo do tipo baja

Abstract

The Society of Automotive Engineers (SAE), promotes events in that university teams participate in order to encourage qualifications in the students. One of the events is related to an off-road competition, BAJA SAE Brasil is a challenge that consists of some championships between teams who design an off-road vehicle, in the championship, there are many trials that the team will participate in order to get, the victory and the qualification for the international championship. Regarding that, this work proposes the design codes using the software MATLAB, for the steady-state lateral dynamics analysis, a design and analysis of the steering torque and how this affects the steering system design and the design of the rack and pinion mechanism to the IFPI Baja SAE team. The first analysis was executed by comparing the data of previous prototypes and a model from a team from Rio de Janeiro, for then analyzing the driveability and which parameters are crucial for the design. For the second objective, the analysis of the steering torque was defined with different input data and how they relate to each other. For the third objective of this work, was produced three codes in a function mode that execute the calculation and the processing with regard to the input parameters introduced by the usuary. In this way, the models designed made satisfactory results, compared with another work that did all the calculations without the “functions”.
