metadata.artigo.dc.description.abstract: Due to the structural constraints of wheelchairs for users with motor disabilities, it is essential to understand and ensure their proper functioning for the quality of life of these users. The main objective of this study is to analyze the stresses and displacements in a wheelchair using the finite element method to evaluate its functional and structural aspects though simulations. Influenced by normative techniques that consider ergonomic, anthropometric and biomechanical, factors were considered to verify the compliance of this equipment considering current standards. Results were compared with experimental analyses performed by the Brazilian National Institute of Metrology, Quality and Technology (INMETRO). Results showed that von Mises stress limit values were exceeded in the chair frame by 6.5%, in the collision analysis by 72.1%, and in the footrest by 189.4%. This indicated that the structure of the analyzed wheelchair is not adequated based on simulation results, same as INMETRO reports.
