Diseño y construcción del bastidor y sistemas mecánicos de un vehículo monoplaza para la movilidad de personas en silla de ruedas.

Abstract

As an alternative to improve the mobility of people in wheelchairs, the frame and mechanical systems for a one-seater vehicle were designed and constructed using design and simulation software, the development of this technological proposal began with a Bibliographic review and information gathering with the objective of identifying the requirements of the users to establish criteria and design parameters, by means of a selection matrix the material suitable mainly for the frame was chosen. That was the structural steel ASTM A-500; once the design was conceptualized; various performance tests of the most critical elements were carried out with various loads by means of simulation software and finally the construction through manufacturing processes such as welding Electrical SMAW and MIG for the assembly of the different elements. When performing a software analysis, satisfactory results were obtained, the frame and other elements were subjected to stresses below the elastic limit as well as its safety factory guarantees the integrity of the user even in extreme cases of an impact. Finally, the chassis and mechanical components were obtained, so it was concluded that the vehicle can be used by standard wheelchair users who present paraplegia or temporary injuries in their lower extremities in compliance with their Requirements It is recommended for future designs to consider lighter materials to those used in order to reduce the weight of the vehicle for a lower energy consumption by the propulsion system and at the time of design consider that the geometric dimensions Can be made with the available equipment.
