Diseño e implementación del sistema de suspensión mediante métodos de elementos finitos y herramientas CAD para un vehículo solar de competencia.

Abstract

The present research work was carried out with the objective of designing and implementing a suspension system using finite element methods and Computer Aided Design (CAD) tools for a solar vehicle at School of Automotive Engineering ESPOCH. It started with the analysis and research of Regulation from Atacama Solar Challenge (ASC); in order to determine the characteristics as materials, dimensions, spaces, and security with which must have the system of suspension of competition solar vehicle. They were made calculations applied based on estimated weight from vehicle (400kg), loads transferred to axes of prototype were determined on slopes, and under braking for determining the forces acting on suspension system, both front and rear. The components of suspension with their respective anchors modeled using Solidworks 2016 and Ansys software Workbench 18 for the simulation of static forces and determination of safety factor in each of these components. The construction carried out once the AISI 304 stainless steel material selected in platens and tubes for the preparation of suspension tables and rear frames respectively for implementing to the solar vehicle. It made tests carried out In order to check the efficiency and safety of the suspension system, displacement, resistance and route. In conclusion, it had a suspension system that meets all the requirements and needs about solar prototype with a total weight of 370kg prototype. Finally, it recommends not exceeding the weight limit for which the vehicle designed, as it may cause faults in the behavior of the vehicle.
