SIZING OF THE TRANSMISSION SYSTEM OF A COMPETITION FORMULA SAE PROTOTYPE

Resumo

The automotive industry is always seeking to improve its processes and technologies in order to obtain
better performance and efficiency in its vehicles, accompanying this growing optimization arises the demand for
professionals increasingly specialized and prepared to assume such responsibilities. One of the main subsystems
in a competition prototype is the transmission system. The transmission system is responsible for converting the
mechanical energy coming from the engines into kinetic energy. This work aims at an approach on the design of
the transmission system of a Formula SAE racing prototype. For the sizing of the proposed system, the first step
was to identify the loads that will act on the components. And from them it was possible to define the geometries
of the projected components and the selection of components not projected. The design of the components not
only involves the values of the loads, but also aspects such as weight, ease of assembly and maintenance,
interactions with other subsystems such as structure and suspension, spatial dimension available for the
transmission system, adaptation to the rules of competition, ease of manufacture and cost of material used. The
use of CAD and CAE software in the dimensioning of the components was of paramount importance in terms of
the need to know the behavior of complex components by means of loads, as well as to validate and verify the
compatibility of the results found.
