Abstract

This paper presents a mathematical and dynamic model for a testing platform designed to assess the performances of a wide range of artificial knee joints (prosthetic and robotic devices) based on the analysis of motion of lower limbs. Fundamental equation of motion for the testing platform which considers the rolling resistance coefficient is being presented. The angle and distance trajectories were set up to run an inverse dynamics analysis, with the target trajectory set as a sinusoidal signal. Variables are introduced and used in the modelling and analysis. It can be concluded from the simulation results that the proposed virtual model of the prosthetic knee testing platform is a very useful optimizing method as a dynamic model for control system design with its advantages of simplicity, validity, and accuracy.
