CHARACTERISATION OF WALKING LOADS FROM INERTIAL MOTION TRACKING

A 3D inertial motion tracking technique, originating from the movement science and entertainement industry, is applied for the analysis of the walking behaviour of pedestrians.The experiments in laboratory conditions simultaneously register the ground reaction forces and the motion of the test-subject.Based on this registered motion, the main step frequency and strideto-stride variations are identified.The ground reaction forces are subsequently simulated using a step-by-step load model available in literature.It is shown that accounting for the identified imperfect walking behaviour of the test-subject leads to a significantly improved agreement between measured and simulated ground reaction forces.
