ABSTRACT
The paper proposes a model of a fatigue device for testing dedicated to ankle prostheses. The concept of the testing device relies on two aspects: almost any type of ankle prosthesis can be tested on it and it has to work on INSTRON axial-torsion testing machine. Starting from these requirements, a 3D functional assembly that reproduces the real movement of the ankle joint during gait cycle has been designed. The device is based on a cam-follower mechanism.
