Abstrakt
Knowledge of dynamic forces acting on the upper limb is useful, and
sometimes even necessary, in its treatment and rehabilitation after injuries, during
prostheses designing, as well as in optimization of the sports training process. In this
work an attempt to determine the quantity of the inertia forces generated in forward
fall has been undertaken. For this purpose a simplified mechanical model of the
human body biokinematic chain has been prepared. Geometric data and mass of each
element have been taken from anthropometric atlas for the Polish population.
Kinematic data necessary to perform the analysis was calculated using fundamental
laws of Mechanics. In this way accelerations of the selected points necessary for the
determination of inertia forces acting on the individual links of the model were
yielded. For validation of the obtained results a numerical model was constructed
using SimMechanic module of the Matlab Simulink software. It made possible to
compare the results obtained in both simulation methods. To make joints model more
realistic a values of the viscous friction were assumed.
