Desenvolvimento de uma bancada de teste para avaliação do sistema de transmissão de um protótipo Baja SAE

Abstract

The transmission system is fundamental to vehicle performance, being responsible for conver- ting and transmitting the power generated by the engine to the wheels. In the context of the Baja SAE competition, the performance of the transmission has a direct impact on the efficiency of the prototype. This work proposes the development of a test bench for the transmission of a Baja SAE vehicle, using an automotive alternator to convert mechanical power into electrical power, with a constant resistive load. The test bench includes electronic sensors for data acquisition and processing, allowing the characterization of the power curve delivered by the transmission system, from the engine to the wheels. The main objective is to compare the engine's nominal power with the power transmitted to the ground, identifying the losses associated with each powertrain component, such as the CVT (Continuously Variable Transmission) transmission, gearbox and axles. The methodology adopted involves carrying out tests to analyze transmission losses. The results obtained will provide valuable information for optimizing the performance of the transmission-engine combination, helping to improve the prototypes in future competitions.
