Análise do balancim da suspensão do protótipo fórmula SAE por método de elementos finitos

Abstract

This work aims to study the rocker. This is a device of the suspension of Formula SAE vehicle that receives efforts from the motion scrolling of the vehicle and transmits them to the chassis frame minimized by a momentum ratio and smoothed by the set spring-damper. A review of parameters used in vehicle dynamics and a geometric analysis of the forces and stresses caused by suchwas carried out. Then, the analysis by the finite element methodwas applied. This analysis uses the theory of discretization of systems and examines the strength of the component based on the distortion energy, determining the maximum straining experienced by the component and the region of higher demand. The main function of the rocker, which is to reduce the force transmitted to the chassis due to roll movement and consequent application of the suspension, is taken as satisfactory, since the force applied to the wheel and which would be transmitted to the chassis is reduced from 3833.9N to 3496.48N to the mechanism formed between the rocker. The rocker resistance to stresses caused by the forces imposed on him was also served to the satisfaction of the material selected to manufacture, since the calculation of security factors for static load prove such a claim.
