Diseño y construcción del bastidor y carrocería de un prototipo de vehiculo impulsado por energía solar para la competencia en el World Solar Challenge.

Abstract

In this research, the proposal is based on with the objective of designing and constructing the frame and body of a solar vehicle of competence; for this the following methodology is applied as an analysis and compilation of Regulations Solar and Atacama Race. Design the frame and body using CAD (Computer Aided Drawing) and FES (Finite Element Simulation) software. Build the frame and bodywork by selecting the right materials. The analysis about Regulation is made to determine the characteristics of solar vehicle, such as: dimensions, spaces, and safety. The software is applied for the design of elements like: Solidworks and Ansys; CAD model is made in the Solidworks and Ansys is used to simulate the behavior frame and the bodywork before static and aerodynamic efforts. In the selection materials, it was determined by destructive tests that the 6061 Aluminum T6 is the suitable material for construction of frame: the construction is determined that the fiberglass is the material suitable for its construction. The result obtained was a vehicle that meets the requirements of regulations of solar competition and with the design parameters established in the present titling work, among which we can mention the following: weight, dimensions, space and ergonomics, safety, speed and aerodynamics of vehicle. Therefore, it was obtained in the static, dynamic and aerodynamic analysis performed in the Ansys and also in the tests of applied tensile and compression. In conclusion, the design and construction of frame and body were realized without any inconvenience and a light, rigid and aerodynamic vehicle. Finally, it is recommended to give continuity to the construction of the solar vehicle through development of titration works, such as: Design and Construction suspension of the vehicle based on aluminum 6061-T6.
