Análise de tensões do joelho de uma prótese transfemoral via método dos elementos finitos

Abstract

The increasing number of lower limb amputations and their consequent change in the quality of life of these people are the precursors of this project. From the theoretical concepts of biomechanics and prostheses, there will be performed a stress analysis via Finite Elements in order to facilitate the understanding of the study. The main objectives of using a lower limb prosthesis are to promote a comfortable, safe and natural gait for the user, in the most diverse activities that he/she wishes to perform. From a theoretical background on the subject, including its current context, the physical structure of the knees with their respective body plans will be presented. The evolution of prostheses and their types will also be presented, since each basic level of amputation receives an indication of specific prosthesis given by a medical and technical team. Finally, the analysis via finite elements in relation to the frames that act on the limb will be presented. In this way, it will be possible to calculate and analyze the efforts in an organized and structured way, allowing the tabulation of data and subsequent results’ authentication.
