Rediseño de un chasis y puesta a punto de un vehículo fórmula SAE de la carrera de Ingeniería Automotriz de la ESPOCH.

Abstract

This work is about the compliance with SAE (Society of Automotive Engineers) rules when designing and constructing a race car chassis. It aims to promote group work and put students’ knowledge and skills into practice, collecting information determined the chassis features to improve performance and efficiency. It must also be easily manufacturable complying with SAE rules. Modeling was performed in SOLIDWORKS establishing ergonomic parameters for drivers according to SAE rules about safety and protection features a prototype must have. A simulation was dome with ANSYS to show the resistance to strees at specific points established by rules. The strees analysis showed that the designed chassis resists all the stress established by SAE. The dynamic impact simulation determined that a speed of 50 km/h causes a deformation of 3.65 mm, but the maximum deformation is 25mm. Therefore, it is concluded that the design is in perfect conditions. ASTM A500 steel was chosen for the construction. Besides, a GMAW welding process will be used for the joints, and after that, the prototype will be constructed.
