Abstract

EN In this paper, natural frequencies of a three-layered foot prosthesis are investigated. The model of foot prosthesis consisted of a three-layered base, which substitutes a human foot and an element in the shape of an arc that represents a shank of human. The base consists of three layers made of carbon fiber. In the lower part of the prosthesis, the auxetic layer is used as the inner layer. Numerical analysis is made for different parameters of the central layer: the thickness and the value of Poisson’s ratio. The simulations are used to investigate the influence of an auxetic layer on prosthesis vibrations and compare the impact of different parameters on results. Calculations are made using the finite element method implemented in Autodesk Fusion 360. The results show that the auxetic layer has a great impact on tolerance to vibrations and mobility.
