Lecture: A Review of Hand-Arm Vibration Simulation Approaches
Author(s): Scholz Magdalena, Moheit Lennart, Marburg Steffen
Summary:
Hand-arm vibration is the interaction of a vibrating device with the hand touching it and consequently propagation from the hand on through the arm. Simulating the process, several aspects have to be considered and it has to be evaluated whether to approximate, to omit or to reflect them in detail in the model. Several different approaches have been suggested in literature. Some reflect the approximated geometry of the hand and arm, while others simulate the hand and arm as a mass-spring-damper system and others represent the anatomy in varying depth of detail. To use those models the excitation of the hand-arm system, i.e. the vibration induced to the hand, has to be known. The effect of the coupling between the device and the hand-arm system on the respective excitation and hence the perception of the vibration, has yet to be investigated. As more and more aspects of devices are optimized, such as the sound and the appearance, other aspects like low vibrations that have been less prominent so far will receive more attention. In order to design and evaluate not only the acoustical and the visual aspects of a product, but also the vibration, the models as well as measurement procedures have to take the coupling into account.
