Resumo: This study seeks to analyze numerically the structure of a concept mobile device armchair (DPM) to be coupled in the bus that will allow the embarkation of persons with disabilities or reduced mobility. The equipment has electric drive and ability to move a platform with the interior of the bus seat, lowering the same to the curb height/ride where passengers with disabilities can easily be accommodated in this chair and be elevated to the interior of the bus. Numerical analysis aims to obtain the static mechanical behavior of the structure when subjected to three loading conditions, two provided for in national legislation in NBR 15.320 and Resolução CONTRAN Nº 445:2013, and another set for the project. The numerical model and its analysis are processed CAE software for Finite Element Method (FEM), and the ability of the numerical model to represent reality is verified by comparison, in terms of displacement, between numerical result and prototype test, carried out in the laboratory under anchoring conditions of a chair, according to Resolução CONTRAN Nº 445:2013. The prototype tested in laboratory accredited by INMETRO obtained opinion by answering the security requirements for the seat anchorage, and its numerical model behavior compatible with the test. In numerical analysis, the structure of DPM, in general, showed good rigidity and lead to future studies with expected mass reduction equipment.
