Rotina computacional para projeto de mola helicoidal de compressão aplicado a um protótipo veicular do tipo Baja Sae

Abstract

The automotive suspension system is responsible for ensuring more safety for passenger cars or offer better performance for racing vehicles. Knowing that the spring is one of the main components of the automotive suspension system, this work aims to create a computational routine in the Scilab environment, in conjunction with a graphical interface for the design of a fatigue resistant compression helical suspension spring that can be applied to a suspension off road baja SAE vehicle. The routine provides enough data for the manufacturing of a fatigue resistant compression helical suspension spring, from data related to load, size and working life, provided by the user. This set of routines is developed based on machine element theories, in order to allow a better perception and optimization of the referred system, providing the necessary information for a better cost benefit analysis in the choice of the material used and the beginning of the spring physical viability.
