Diseño de un scooter eléctrico como alternativa de movilidad ecoamigable

Abstract

This project aimed to design an electric scooter, through computer-assisted simulation software, showing it as an eco-friendly urban transport alternative. It began designning three chassis alternatives in Solidworks 2021 software, assigning and testing two different materials: structural steel and 1060 alloy aluminum, to obtain the total mass of each alternative. Each alternative was subjected to static analysis in the Ansys 19.2 software, obtaining the directional deformation and Von Mises stress produced by loads of 120 and 200 kg, analyzing their behavior and resistance. The steering system, power train, and other components were modeled to obtain the total weight of the final scooter with and without a seat, which was 15.35 kg and 16.77 kg, respectively. The aerodynamic coefficient (cd) of 0.6 was obtained, and the ergonomic analysis of the scooter was also carried out in the NX 1926 software for three different types of people based on the average height in Ecuador, which is between 1.64 m and 1.67 m, to test its comfort. Finally, the autonomy analysis of the scooter was carried out with three different types of batteries in the ECE R15 full velocity driving cycle, with a surface of 0° and a maximum speed of 14 m/s. It was concluded that the 36V 15.6 Ah lithium battery offers superior autonomy with an average of 55.58 km, alternative 3 with 1060 alloy aluminum is better since it presented less weight and deformations with the assigned loads, and the comfort of the scooter was also demonstrated. It is recommended to use Alloy Aluminum 1060, use the Nx 1926 software to perform the ergonomic analysis, and use a mesh of 6 mm or less for the static analysis.
