• Description:
  The coupling force at the hand-handle interface is measured using a capacitive thin-film pressure-sensing grid. The measured data acquired for a 40 mm diameter handle and 12 male subjects under different combinations of grip and push forces are analyzed to derive relationships between the coupling, grip and push forces. The measured data are also analyzed to study the variations in the effective contact area as a function of the grip and push forces. The results suggest that the hand-handle contact force can be expressed as a linear combination of grip and push forces, where the contribution of the grip force is considerably larger than that of the push force. The variations in the contact area can be approximated by an exponential function of the grip force. The results of the study suggest that the hand-handle contact force can be conveniently estimated from the grip and push forces, which can be measured directly. [Description provided by NIOSH]
