Rediseño e implementación de un asiento de fibra carbono para el vehículo formula SAE de la EIA (ESPOCH) utilizando métodos de elementos finitos y manufacturado por Hand Lay-Up enfocado en reducir la relación peso potencia.

Abstract

The present qualification work is based on the redesign of a seat for the FSAE of the automotive engineering career ESPOCH based on the study of a seat and ergonomic firewall, in the approach of the problem two problems were determined the step and the resistance that are of influence on the behavior of the race vehicle as such, so we opt for the change of original material by an epoxi polymer matrix composite and a reinforcement of glass and carbon fibers that helps to significantly reduce the weight and increase the resistance, The main purpose of the technological proposal is to reduce the power to weight ratio of the EIA car. The CAE analysis is of importance in the present study as it serves as a guide for post-processing, Validated by the results provided by the aerodynamic and static simulation and CFM of computational fluid mechanics for aerodynamic results, for the manufacture of the seat the hand lay-up method is used, which is an open mold process used for the feasibility it provides, three layers of carbon of 600 gr and with Young's modulus of 230 Gpa and a fiberglass layer of 600 gr were used to proportion to the compound a percentage of high elongation giving excellent results at the time of the characterization of the material validity by the center of productive development of mechanical metal and bodybuilding, with respect to the weight ratio of the ability to achieve a 5% reduction, which is a significant difference in favor of the present titling work, achieving the main objective.
