Abstract
According to the current ISO 5349-2 (2001), hand-transmitted vibration (HTV) exposure should be measured using accelerometers rigidly fixed on the vibrating surface in the hand contact areas. If it is difficult to apply this approach. HTV can be alternatively measured using an adaptor held in the hand (ISO 5349-2, 20(1). Compared with the direct approach, the adaptor approach has several advantages if applied appropriately. For example, it could be more efficient for the measurement and less intrusive to the tool operation; hence, it may be suitable for a long-term monitoring measurement. Probably for this reason, the adaptor approach has been considered in the development of some convenient or direct-reading devices for HTV measurement. However, it is not the preferred option in the standardized methodology, primarily because the adaptor vibration could be affected by the inconsistency of the hand-applied forces and the biodynamic response of the hand. The objectives of this study are to find the specific mechanisms of the biodynamoc effects and to identify the optimized design of the adaptor and/or its hand-holding strategy so that the undesired effects could be minimized.
