Análise do semieixo de um carro Fórmula SAE através do método de elementos finitos utilizando o software ANSYS

Abstract

The UTFast F-SAE Racing team came up with the objective of participating in the annual competition of SAE Brasil in 2015, since the car built by the team has some parts adapted from commercial vehicles due to the great difficulty of manufacturing, such as the engine, transmission and axle shafts. To validate this adaptation, the finite element method was chosen to carry out a study with the semi-axis. Data relevant to the work were provided by the UTFast team, such as the car's torque, transmission manipulated reductions, axle shaft dimensions, among others. Thus, it was possible to carry out the CAD drawing of the part and a study of the forces that operate on the car. The finite elements method was used to study the semi-axis, which was developed in the ANSYS software, which shows how the stress reaches the component through the help of Von Mises, which is the objective of the work. The simulation of the finite element method in ANSYS fulfilled the objective proposed in the work, showing that there was no flow in the semi-axis. It was also possible to analyze smaller sizes in which they could be used, aiming to reduce weight in the competition car.
