Diseño y construcción de un sistema desmontable para facilitar la movilidad de personas con capacidades especiales hacia el interior y exterior de los vehículos tipo sedan utilizados en AFAPECH - Riobamba.

Abstract

This work was carried out in order to design and build a removable system to facilitate the mobility of disabled people of AFAPECH (Association of Relatives of Exceptional Persons of Chimborazo) to the interior and exterior in a sedan type vehicle, in response to the problem of scarce available equipment that facilitates their mobility to the vehicle, and in this way to reduce the injuries by repetitive efforts in the persons in charge of carrying out said activity. For which, the requirements were identified by the association which allowed the design of a removable mechanism, with electric actuator with its respective joystick control module, supported on the hinges of the passenger door using an orthopedic harness. The selected material with which the equipment was built is ASTM A500 carbon steel. With the help of CAE software, the design was validated through stress analysis, deformations and safety factors to guarantee the reliability of the equipment. Three tests were carried out with people of different weights and statures in which the different components of the system were not affected and worked correctly without showing anomalies, on the other hand the users reported comfort during this stage. It can be concluded that this mechanism can be used by disabled people who have control of the movement of their head. In order for this work to achieve greater coverage with most vehicles, it is recommended to design and build other types of supports on the hinge for each category of vehicles.
