A five-degrees-of-freedom model of the hand-arm system comprising two driving-points formed by the fingers-handle and palm-handle interfaces is applied to predict biodynamic responses distributed in fingers, palm-hand-wrist, forearm and upper arm, and shoulder. A set of mechanical impedance data measured at the fingers and the palm of the hand under four different hand actions (50 N grip-only, 15 N grip and 35 N push, 30 N grip and 45 N push, and 50 N grip and 50 N push) was used to construct the model of hand-arm system. The proposed model permitted for analyses of biodynamic responses in terms of mechanical impedance and power absorption, distributed in different substructures of the hand-arm system as functions of the hand forces. The proposed methodology permits for exploring the relationships between the location-specific vibration-induced disorders and the substructure specific power absorption.
