Diseño y construcción de la estructura tubular para la carrocería del prototipo de un auto eléctrico BIPLAZA UTA-CIM17

Abstract

This project is of great interest from the innovative point of view as it contributes to the growing tendency to project towards the use of non-polluting energies such as the use of fossil fuels. The present project was elaborated in some phases, first designing the geometry considering spaces and distribution of components, the selection of the material was very important considering some materials it was decided to build the floor of the interior, the front and back with galvanized structural steel pipe ASTM A-500 of (30x30x2) mm and the ceiling with tube (25x25x1.5) mm, based on these parameters it was needed a CAD / CAE software to visualize the design and the forms, the next phase was to calculate the states load that would be subject to the structure such as vertical loads, braking, acceleration, rotation, resistance to wind and torsion, with the values of the loads was proceeded to simulate with the help of the ANSYS student version program to obtain results of displacements, Von Misses effort and essential safety factors for the design. Finally, in the construction phase, the selected profiles were cut and welded using GMAW ER70S-6 welding, while the structure was assembled also the other subsystems accompanying the structure were assembled as suspension, propulsion and steering.
