Diseño y construcción de un prototipo de carrocería de autobus, sobre un chasis compacto modificado autoportante.

Abstract

This project proposes the design and construction of a bus body prototype in a modified compact self-supporting chassis. It seeks to expand the warehouse space of conventional buses of this type, through a cut in the frame of the chassis prior authorization from the manufacturer. It was proposed because of the problem in the public transport of not having enough space to carry luggage in the holds. By presenting the steps for the execution of the project, with the validation and justification of the process for the construction of the prototype, the authorization of the chassis manufacturer is obtained. The prototype is built based on the design plans according to the development of the Engineering part by validating the model using CAD and CAE software such as Ansys, LS-Dyna and LS-Prepost. Once the prototype is built, the bus is approved in compliance with the parameters of the applicable Ecuadorian regulations. Through the homologation it is concluded that the model achieves the fulfillment of the main objective by achieving an increase in the warehouse space approximately 19% higher than conventional models of this type. The established research is framed within the line of technological, artisanal, and industrial processes, specifically in Automotive Design. The proposal of a new bus that will allow to have a different option to those currently existing, being an innovation in the area of transport buses, thus comply with the proposal and development of a solution practice to the given problem.
