MATHEMATICAL DESCRIPTION OF BEHAVIOUR OF A HUMAN BODY DURING WALKING – STANCE PHASE

Abstract eng:
The presented paper deals with a mathematical description of behaviour of a human body during walking. Especially the work is aimed at the stance phase of walking process, where the pedestrian’s foot is in permanent contact with the ground. If we simplify the human body as a mass point, which is placed in the CoM (center of mass), we are able to state that the pedestrian is acting as an inverted mathematical pendulum, which means that mass of the pendulum hinge is neglected. Thus the vertical force component in the hinge of inverted pendulum corresponds to the time behaviour of the contact force experimentally observed. The simplified pedestrian model was considered as two dimensional, defined in the plane of walking. The solution of this problem was executed in the central gravity field.
