Optimization of the shape of the sports prosthesis

Abstract

This research is about the shape of a sports prosthesis. More than half a century has passed since the first Paralympic Games in 1960. During that time, the record and competitiveness of prosthetic leg runners in sports for the disabled have improved. Improving the technology of sports prosthesis is helping to improve the competitiveness of sports for the disabled.The stress and displacement of the sports prosthesis are analyzed with the finite element method analysis software. It turns out that sports prostheses have spring-like characteristics. We used the stiffness ratio for this result. In addition, we examined how the sports prosthesis could be deformed to have more spring-like features. We found an area to be reinforced from the displacement. As a result, we created a new shape of sports prosthesis. And the prosthesis has a big spring-like feature. In this way, this research aims to optimize the shape of the sports prosthesis.
