Knee analysis to determine physical parameters on structures exoskeleton

This paper presents a biodynamic analysis of knee in the time-domain by trigonometric methods, we consider relevant aspects of gait analysis, also the sit-to-stand movement that consist in lift the body from a chair, and finally the consequences that produce linear and angular movements in this joint. We validate our model with simulations and experimental results, so that can add movement to an exoskeleton structure in analysis region with parameters power, torque, speed and tenacity. The percentage error from model takes as reference the simulation results, this part have statistical data that provide anthropometric measurements and aim to give approximate results for individuals who can adopt this type of active structures.
