Abstract
The aim of this work is to analyze the tube frame (chassis) of a baja SAE vehicle used for Petrobras competitions of northeast regional and national round. Through the study of finite element method, it was possible to obtain simplifiers results for the construction of the project. The finite element method consists of splitting a body, creating a mesh consisted by several parts or elements defined by the user. This technique allows complex calculations of deformation, displacement and stresses in the structure, obtaining approximate solutions that can be close to real values, regardless its loading. The chassis is the basic component of an automotive vehicle. It consists of an internal structure that receives all the other components, and it must withstand all mechanical loads, in order to ensure safety for the passengers, the correct closing of the doors and the operation of the steering and suspension systems [1]. The model to be studied was developed before the security regulation set by the SAE (Society of Automotive Engineers), using a CAD (computer aided design) software, thus, it was possible to make the chassis modeling applied to the vehicle type baja. After the modeling, simulations were performed in a CAE (Computer Aided Engineering) software, in which it has been assigned to the type of material, loads (forces), type of mesh, and predefined conditions of the structure, supposedly where front and rear suspension will be assembled.
