Diseño e implementación de los pontones de un vehículo de competencia fórmula SAE mediante fibra de carbono para la carrera de Ingeniería Automotriz de la ESPOCH.

Abstract

The present abstract has got as main objective to get this technological proposal in order to implement the Formula SAE car race vehicle pontoons applying carbon fiber to run during ESPOCH Automotive Engineering car race through getting the SAE 2017-2018current regulation and with this to get some restrictions to use for its corresponding manufacturing process and design besides it was researched the suitable characteristics must be fulfilled to generate a very good aerodynamic performance that was why there were manufactured there designs taking into account Solid work software to model that through CAD, after getting designed those it was analyzed each model performance while they were interacting with air through ANSYS 18.0 Fluid Flow packet where it was simulated those there designs performance to continue afterwards selecting the most suitable basing on those characteristics related to the car race vehicle aerodynamic part, such as a low dragging coefficient through eliminating some disturbances generating a suitable lift coefficient for the most part addressed towards the floor effect and which will get the engine and radiator refrigeration. After having tested its efficiency and functionality it is going to proceed with the corresponding manufacturing where some timber was used to obtain the negative matrix to manufacture the two-dimensional carbon pontoons saturated whit epoxy resin 65 % (pofix 300 A type)adding catalytic converter 35% B type, this whole process must be taken into account through wheel drive, deflection and impact by fulfilling ASTM regulations in the same material test piece in order to get a polyurethane well planned professionally completed and painted exterior similar to that from the conventional vehicle. As a result its design was improved, it was possible to get the appropriate rigidity and the pontoons functionality getting to become efficient and improving the SAE Formula aerodynamic vehicle.
