A Laboratory Study of a Low-Cost System for Measuring Coupling Forces /

25 Apr 2016

The recommended guidelines, however, do not account for the effects of the coupling forces exerted at the hand-handle interface, although many studies have shown the importance of these forces in the transmission of vibration to the hand-arm system. [...] The measurements, however, revealed strong dependence on the loading area, position of the load on the sensor, length of the sensor and flexibility of the loading media (elastomer). [...] The coupling forces associated with the operation of vibrating tools generally consist of two components: (i) the static hand forces applied to achieve essential control and guidance of the tool and to achieve desired productivity, which has been the primary focus of ISO 15230 [9]; and (ii) the dynamic force arising from the biodynamic response of the hand-arm system. [...] The study showed insignificant differences between the acute effects of the hand grip and push forces, and thus recommended the sum of the two to derive the coupling force. [...] The through-the-hand-arm response function describes the transmission of vibration to different segments of the hand-arm system, expressed as the ratio of the vibration magnitude measured at a specific segment on the hand-arm system to that at the hand-handle interface [11].
