Projeto e dimensionamento de suspensão de um veículo de fórmula SAE

Abstract

Designing a suspension for a Formula SAE vehicle is a pivotal challenge in optimizing the performance and safety of this type of competition automobile. The research encompasses a detailed analysis of the most common types of suspensions used in these vehicles, highlighting their characteristics, advantages, and disadvantages. Initially, different suspension designs such as independent suspensions, double A-arms, McPherson, among others, are explored, providing a comprehensive understanding of their structures and functionalities. Each configuration is examined concerning its ability to handle the specific demands of a competition vehicle, including agility, grip, control, and comfort. Subsequently, the study delves deeper into analyzing the forces and moments acting on the suspension components during vehicle operation. This critical stage allows for the identification of the maximum stresses these suspension components endure. Based on these force and moment analyses, the study proceeds to computational simulations where the identified maximum stresses are used to predict and analyze deformations in the suspension parts. The ultimate goal of these simulations is to ensure proper sizing and structural strength of the suspension, verifying whether the components can withstand mechanical demands and anticipated loads. At the end of the study, conclusions are drawn regarding the sizing of the trays, tie rods, and scaffold based on the maximum simulated stresses in these components, providing a safety factor of approximately 1.3, sufficient for the suggested suspension production outlined throughout the study.
