Diseño y construcción de una carrocería de un vehículo de competencia fórmula “SAE” en fibra de vidrio, para la Escuela de Ingeniería Automotriz.

Abstract

The analysis and the bodywork construction for a racing car Formula SAE has as objective to promote teamwork and encourage research in participants to achieve new knowledge and skills that enable to excel at national and international level in this prestigious competition. The essential characteristics that a prototype should have for optimal performance were established through the application of different methods of data collection, with the possibility to assemble the chassis easily and comply with all regulations that are required for Formula SAE to be allowed to participate in the competition. With the help of SOLIDWORKS software, the respective modeling was performed with emphasis on details that could affect the proper functioning of the whole and then analyze the model in ANSYS software to simulate different forces that occur in different conditions and analyze deformations and maximum efforts produced, to achieve and determine an appropriate safety factor. In the construction process the manual layering technique is applied by using a composite material which contains 40% of glass fibers as reinforcement to obtain the expected results, providing resistance and proper weight for the model, even performance in any working conditions with aerodynamic geometries that help improve fuel efficiency, that is a very important parameter due to it evaluated in the competition. Finally, the model is immersed into an esthetic process in which the colors and emblems to represent the institution are applied.
