Diseño y construcción de un bastidor ligero tipo monoplaza para un prototipo de propulsión eléctrica destinado para investigaciones sobre eficiencia y bajo consumo energético, por medio de simulación y análisis CAE

Abstract

The automotive industry is one of the main sectors of development worldwide, therefore, innovation and the search for new technologies are essential to improve this sector. One of the main approaches currently being sought is to generate new energy sources that provide greater autonomy with a considerable reduction of pollution, being electric energy the most studied, that is where the development of prototypes of electric propulsion plays an important role as it allows to establish bases in terms of efficiency that could be obtained by making adjustments or improvements in the design of the components or the aerodynamics of these. One of the main components in automobiles or any type of propulsion prototype is the frame, which is considered the structure that comprises the fundamental support for the different mechanical and electrical systems, it is also the component that is responsible for supporting the different live and dead loads in the vehicle. With the passage of time, the frames have been presenting considerable improvements to obtain a better adaptability to new technologies by varying the design and construction material managing to reduce the weight of these without affecting their resistance, thus saving material, economic and technological resources which are considered as important factors at the time of making this type of components more efficient. Several studies have shown that the reduction of the mass in the frame structure has contributed considerably to the use of energy resources and the power-to-weight ratio that can be delivered, this goes hand in hand with the design and manufacturing materials because if the constitution is too complex it will represent a problem in the use of resources. This project focuses on the design and construction of a lightweight single-seater frame for an electric propulsion prototype, through a CAD computer-aided design software, a frame design will be created considering factors such as the dimensions of the pilot, the dimensions for the electric drive train and the driving position and construction material, through the CAE analysis is expected to obtain results that ensure that using lightweight materials and with a correct design a frame can be light and can withstand specific loads without permanent deformation.
