SIMILARITY IN DISPLACEMENT OF THE BAR WITH CIRCULAR SECTION ON THE INCLINED AXIS OF THE PARALYMPIC WHEELCHAIR

Abstract

The analytical solution of several practical problems in engineering is difficult to perform, and must be solved numerically or experimentally. Therefore, a great solution is experimental modeling. Based on dimensional analysis, which is based on the methods of measurement and analysis of physical problems, similarity is developed. This work aimed to find a predictive equation that makes it possible to determine which would be the deformations suffered by the axis that could influence the performance of the person with disabilities during their commuting. To validate the process, a finite element software was used to simulate the chair and change all the variables involved. Finally, a general predictive equation was raised and made it possible to predict behaviors that could be corrected with small adjustments by simple calculations.
