BRAKE SYSTEM DESIGN AND DELEVOPMENT FOR FORMULA SAE COMPETITION VEHICLES

Resumo

SAE is a Society of Mobility Engineers that, in partnership with several companies in the automobile
industry, promotes the Formula SAE competition. That is the biggest competition among engineering students,
and started in the USA in 1981, expanding to several countries, such as Australia, Germany, Japan and Brazil. In
this context, several students from various universities propose to develop formula like prototypes, to use the
knowledge acquired in the academic scenario and good engineering practices. For security and control issues, SAE
defines rules that must be followed by the teams. One of the main subsystems is the brake system, which must be
hydraulic and composed of two independent series. The brake system is evaluated both in technical tests (technical
inspection) and dynamics tests (braking). This paper shows the design and construction of a robust, effective and
low-cost brake system, with well-defined criteria, from its initial conception to its manufacturing. Therefore, it is
necessary to study the dimensioning and the forces that make up the entire system. The acquired data allows us to
perform an experimental validation and make a comparison between the theoretical and experimental models, to
understand the system and identify possible problems and evaluate its performance.
