Análise da dinâmica vertical de um protótipo BAJA SAE e modelagem em ambiente multicorpos.

Abstract

The present work consists of the study of the vertical dynamics of a Baja SAE off-road vehicle. Starting with the computational modeling of a quarter car model and in a multi body environment, the first, in the XCOS extension of the Scilab software, and the second, in ADAMS Car environment. Both tools reproduced the test performed on a track with the BAJA UEA Team 2022 prototype, as well as all its parameters. This test depicts a track with a "bump" obstacle and the goal is to create a stimulus in the suspension system. For the experiment with the prototype, a sensing system was used to acquire data such as: acceleration, velocity and vertical displacement of the vehicle components, which will later be analyzed comparatively with the data obtained in the computer simulations in order to analyze the accuracy of the models created. In addition, important system parameters will be modified in order to analyze the impact on comfort.
