Finite Element Analysis of a Transtibial Prosthesis for a Paralympic Cyclist

Abstract

Nowadays, finite element analysis techniques are employed are used to reduce costs in the manufacturing process of sports prostheses. This study particularly focuses on the finite element analysis of a design for a transtibial prosthesis of a paralympic cyclist, in which integrated the biomechanics of an athlete with amputation in both legs below the knee with two prostheses categorized before the Union Cycling International (UCI) with a disability of degree C-3, considering the characteristics of the terrain and the dynamic model. The analysis by means of finite elements aims to evaluate the static and dynamic behavior of the proposed design when subjected to a competition in the track-cycling category. As a result of this analysis, mechanical aspects such as: static forces, buckling, frequency, fatigue, free fall, impact and aerodynamics can be evaluated, allowing to verify that the design of the proposed transtibial prosthesis meets an suitable aerodynamic profile and its mechanical characteristics to be used in a high performance Paralympic cycling competition.
