• Description:
  Vibration transmissibility on the hand-arm system is very important to understand and simulate the biodynamic response of the system. Such knowledge can be further used to help understand vibration-induced discomforts, injuries, and disorders. While the mass of the conventional accelerometers could significantly affect the measurement of the transmitted vibration, some single-axis laser vibrometers have been used to measure the transmitted vibration (Sorensson and Lundstrom, 1992: Deboli et al., 1999; Concettoni and Griffin, 2010). However, the transmitted vibrations excited from multi-axes vibrations have been far from sufficiently studied and understood. Further simulations of the system also require multi-axes transfer functions. Therefore, the objective of this study is to investigate the vibration transmissibility on the human hand-arm system subjected to vibrations in three orthogonal directions (Xh. Yh, and Zl) Some preliminary results and their interpretations are presented in this short paper. [Description provided by NIOSH]
