Diseño de una silla bipedestadora para terapias de rehabilitación y reeducación física para personas adultos con un peso máximo de 100 Kg

Abstract

The objective of this project is oriented to the design and construction of a standing chair with a load capacity of 100 kg for physical rehabilitation and re-education therapies. This standing chair is designed for people who suffer from a temporary problem that makes mobility of the lower limbs impossible, with which it is sought that the user receives adequate therapy in it. For the design of the structure, the anthropometric measurements of the average Ecuadorians were considered and through SolidWorks a design of the base structure of the chair was obtained, the standing mechanism called four bars was obtained by analyzing the Grashof condition, simulating and validating its different properties in Matlab and Adams, which guarantees correct functionality and, above all, security for the user. With the CES EduPack software, the material that best fits the needs of the prototype was obtained, with the help of finite element analysis, the dimensioning of the elements that make up the standing wheelchair was obtained. The linear actuator is selected according to the needs of use and referring to the fact that it will be used by people with temporary disabilities. Finally, the standing wheelchair has standard measurements of commercial wheelchairs, the standing mechanism has a quite efficient and safe design, which allows the user's standing position to be comfortable and reliable enough to carry out physical rehabilitation and re-education therapies. It is recommended to carry out a previous meshing study in SolidWorks to validate the data obtained.
