Diseño e implementación de una carrocería en fibra de carbono y resinas termoestables mediante el uso de software CAD/CAE para un vehículo solar de la Escuela de Ingeniería Automotriz.

Abstract

It was designed and implemented a car body in carbon fibre and thermosetting resins for a solar vehicle of the Automotive Engineering at the ESPOCH; it starts from the investigation and the necessary rules analysis for the solar vehicles competition in the World Solar Challenge (Australia) and for the Solar Race of Atacama (Chile), in aspects like the material selection, the construction parameters, the vehicle dimensions, and the security. The car body was designed in SolidWorks 2017. The static, dynamic and aerodynamic efforts simulation was made with the software Ansys Workbench 18, 2. The carbon fibre selection was determined through the material characterization, the carbon fibre 3K Twill is a suitable fabric for the car body construction thanks to the great advantages that this sort of fibre gives, reinforcing the structure and adding a minimums weight. It was gotten a car body that supply the requirements of the competencies of the solar vehicles and with the stablished parameters for the present technological proposal design and implementation, among which we can mention the following: rigidity, weight reduction, car body structural design improvement and the aerodynamic of the vehicle. The cd valour is of 0.25035 which shows that the vehicle presents little resistance to the air. In conclusion, the car body design and implementation did not present too much inconvenient, and a rigid, light, and aerodynamic car body was gotten. Finally, it is recommended to continue with the solar vehicle construction with other titillation works realisation, like for example: suspension system design and implementation, electric motors implementation, photovoltaic panels, etc.
