Diseño, simulación y construcción de la carrocería de un prototipo hibrido ecológico de tres ruedas usando técnicas CAD, CAE, DFC, empleando fibra de vidrio

Abstract

In this technological proposal, the design, simulation, and construction of a fiberglass bodywork for an ecological hybrid prototype of three wheels was conducted to reduce weight and manufacturing costs. The computerized design was carried out with the help of the software NX 12.0. Then the test pieces design was developed in SOLIDWORKS 2019 software to perform flexural, traction, and impact tests using the ANSYS 18.2 program to know the breaking points. Then the aerodynamic analysis was carried out to know the maximum speed that the vehicle was capable of coping with before destabilizing. The use of various information-gathering methods allowed to establish the essential characteristics that the material must have for the manufacture of the bodywork so that it can be easily assembled to the chassis. The manual stratification technique was applied in the building of the bodywork, using fiberglass that contributes 40% to the composite material as reinforcement, providing the resistance and adequate weight for the optimal performance of the vehicle with aerodynamic geometries to improve its efficiency. Finally, the aesthetic stage was performed with representative colors and emblems of the institution. It is concluded that fiberglass bodywork is a profitable option due to its low cost, lightweight, and malleability. Thus allowing a varied application in the construction of various objects such as bodywork.
