Abstract

The aim of this internship is to develop a theoretical model of wave propagation through a 1D beam representing wave propagation through a prosthesis to the athlete during the T64 long jump. To do this, a first study of wave propagation in several materials was carried out using the conservation of forces and displacements at each interface, to then be able to make a first simple model consisting only of the socket, the prosthesis and the residual limb. A second model was then made from this first one, to which a mass was added at the end of the residual limb representing the athlete, and then a final model based on the second one, to which the floor was added in the form of a variable section beam. This last model shows that in order to minimise the risk of injury, a material with a low modulus of young and low viscosity is required. As this research is aimed at minimising the risk of injury, it should be compared with other research aimed at maximising performance. Furthermore, this model is theoretical and therefore requires experimental verification.
