Diseño y construcción de los sistemas de chasis, carrocería, dirección, frenos y suspensión para un vehículo monoplaza eléctrico

Abstract

This project aimed to characterize the chassis, power train, steering, brake, and suspension systems for a single-seat electric vehicle, for which the automotive systems were analyzed and studied in a computerized manner to optimize and adapt them according to the present reality. This process was carried out based on the study and analysis of the topic raised as the degree work. Subsequently, the material for the design and simulation of the first system, which will be the chassis, was chosen. Next, the calculation of the power train was carried out to know the specifications and requirements at the time of incorporating said automotive system. Once the design and simulation were completed, the acquisition of materials, construction of the prototype, tests, and results were carried out as described in the project stage diagram. For the design and characterization of materials, the Solidworks design program was used, where the maximum critical value was obtained in the upper arm of the suspension with a resulting force of 2880N. While for the movement conditions the tool called Ansys was used; where, in general terms, the materials to be used were obtained, such as hollow tubes of 25.4 cm and 22 cm in diameter, in addition to a 10 cm square tube with total lengths of 9.35; 3.91 and 2.97 m respectively. Thus also its limitations to withstand where the maximum case was for the spring grip with a maximum stress value of 101.99 Mpa. It is concluded that the materials to be used will depend on the loads to which they will be subjected because not all systems support the same efforts. It is recommended that the prototype has a use and maintenance manual to facilitate its handling in general.
