• Description:
  Vibration biodynamics of the hand-arm system is one of the foundations for understanding vibration-induced discomfort, injuries, and disorders. One of the approaches to the study of biodynamics is to examine the driving-point biodynamic response of the system. The vast majority of reported studies assumed vibration excitation at a single point on the handle-hand interface. This assumption is acceptable for the analyses of many tools when the overall response is of concern. According to Saint-Venant's principle (Toupin. 1965), this assumption may also be acceptable for the analyses of the dynamic loads in the arms, but it is not acceptable when responses in the vicinity of contact substmctures, especially in the fingers, are of concern. WIllIe some studies on responses distributed at the fingers and palm of the hand along the foremm direction have been reported (Dong et aI., 2005), little information on the distributed responses in the other directions is available. Therefore, the objective of this study is to examine the driving-point biodynanllc responses distributed at the fingers and palm of the hand in three orthogonal directions (Xh,Yh.and Zh).
