Diseño y construcción de la trompa de punta redondeada y atenuador de impacto empleando materiales compuestos para un vehículo de competencia fórmula SAE de la Escuela de Ingeniería Automotriz.

Abstract

The present qualification work shows the design and construction of a rounded tip tube and impact dimmer for a formula SAE competition vehicle. Using software CAD for the design and compound materials for his construction, fulfilling with the specifications of the organization Society of Automotive Engineers, SAE. The software to be used are: SolidWorks for design and Ansys for analysis and simulation, three rounded tip prototypes were made, emphasizing the details that could affect the vehicle aerodynamically, all this with the purpose of analyzing each of the prototypes, determining the design that present a better performance for the competition vehicle formula SAE through the results obtained from the pressure, speed, flow trajectory and turbulence analysis. The dimmer is an element that will absorb the collision energy minimizing the damage to the vehicle and to the pilot, this element is located by regulations on the front of all the cars participating in this competition. The impact attenuator, besides being a safety element it must be light improving the performance of the vehicle with an accessible price to the equipment budget and to have simplicity in its manufacture and assembly. The design and analysis of this element will allow us to obtain results such as: absorbed energy, maximum deformation and maximum and minimum stresses. The competition of Formula SAE requires parameters such as safety of the driver, vehicle safety, material weight, they influence to obtain better results. For its construction composite material will be used since it presents a high mechanical resistance with which we will achieve: impact resistance improvement, greater safety for the pilot, less weight of the competition vehicle to make it more aerodynamically efficient, it translates into fuel savings also. In addition to make it more resistant to external agents, it would avoid special care against rust or the corrosion.
