Item Simulação numérica de uma prótese transtibial do tipo flex para corrida(2024-09-27) Barbosa, Jéssica Natália da Silva; Lins, Erb Ferreira; Oliveira, Edilma Pereira; http://lattes.cnpq.br/5272283698536321; http://lattes.cnpq.br/2366259555737290Prostheses play an essential role in the recovery of autonomy in amputees, allowing the practice of physical exercises essential for physical and mental health. This study analyzed the structural behavior and blade optimization of a flex-type transtibial prosthesis, considering the biomechanics of human gait and the reaction forces of the ground during running. The methodology adopted involved the three-dimensional modeling of the prosthesis, the structural analysis through the finite element method and the optimization through a correlation analysis of dimensional parameters to minimize the stresses on the prosthesis. The results showed that the maximum equivalent stress in the model optimized by the applied methodology showed a reduction of 24.73% in relation to the reference model. The methodology presented allows the construction of prostheses with geometric constraints that simultaneously minimize engineering requirements.Item Análise de tensões em flanges eólicos utilizando ferramentas CAE(2024-03-07) Inocencio, Igor Guilerme Neri; Lins, Erb Ferreira; http://lattes.cnpq.br/5272283698536321; https://lattes.cnpq.br/4975371866385642The growth demand for energy power and the use of wind technology to generate it is a current trend on today worldwide. Seeking to better understand the behavior of a crucial structural component of wind turbines, the present study employs the finite element method to examine stress distribution in the wind tower flange under operational loads conditions without wind action and under extreme wind speeds as speciefied by the International Electrotechnical Commission (IEC). The results highlight stress concentration areas and identify potential susceptibility to fatigue failure, while also assessing the impact of these loads on the structure's integrity. Finite element analysis reveals stress distributions in the flange, with higher concentration susceptibility identified in external regions. The values obtained from this analysis, applied to a fatigue analysis, demonstrate that the flange's safety factors are high for the magnitudes of stresses encountered.
