Abstract

In this study, a human body has been composed as a 6 rigid-open loop-body model which is consisted of a leg, a foot, a thigh, a trunk, an arm and a fore arm. To determine the anthropometric characteristics of the bodies has been benefited from anthropometric models and the computer software. The movements of the subject markers placed on body was viewed with a video camera in order to get location data of joints and the digitization process was made. It was computed the angular displacement, angular velocity and angular acceleration of the joints using by MATLAB (7.6.0). The obtained data was used to actuate inverse dynamics model which is created by SimMechanics (2.7.1). Motion of standing up from the sitting position was simulated by using SimMechanics software. It was compared ground reaction force calculated by SimMechanics with ground reaction force measured by force platform. This study was also shown that SimMechanics software which is developed to analyse mechanical systems in real dimensions dynamically can be used for human motion analysis. Furthermore, the simulating process has been useful to explain kinetic behaviour of the human movement.
