Simulação do comportamento da transmissão de um veículo mini baja

Abstract

The search for comfort, mobility and time saving has always been linked to human nature. As a result of this search, it is currently possible to move from one place to another, near or far, sitting on a leather seat and with great speed. A great invention in history, which can ratify the thought of the pursuit of comfort, was the automobile powered by internal combustion. At the heart of the vehicle's design is the powertrain system; it is the engineering of this system that provides the driving force behind mobility. Regarding powertrain systems, the two main components are the engine and the transmission. In this metric, the following work aims to obtain a code in MATLAB to analyze the transmission of a Baja vehicle through the forces acting on the transmission system and present the results obtained with the simulations made. The design parameters were obtained from the literature and from the IFPI Baja team for the calculations of the proposals in the analysis such as efficiency, precision and maximum tractive force. With that, the characteristic curves of the engine were passed, which demonstrated the maximum torque at 2800 rpm in the amount of 19.32 N.m and the maximum power in the amount of 5.89 kW reached at 3000 rpm. Furthermore, it has been seen that the top speed is 55.94 km/h. Furthermore, a maximum tensile force of 1795.24 N was obtained. With this, the tested analysis proved to be effective, since it fulfilled the main objective of returning crucial data from the transmission system.
