Abstract
This work proposes a mathematical model of the dynamic behavior of prosthetic knees. The model is based on the biomechanics of actual human gait, employing multi-body dynamics tools for representing the studied system. The structure deformations due to contact forces are explicitly taken into account. Simulation results are used to illustrate the main features of the proposed model when compared to those obtained by means of a state-of-the-art commercial simulation package for mechanical systems. As result, the proposed algorithm and the commercial package have similar kinematic and dynamic behavior for free movement, while differ in the contact condition.
