Hand-Arm Vibration: Implications Drawn from Lumped Parameter Models.
NIOSH 1977 Apr:136-141
Models of the hand-arm complex are given; these are developed from mechanical impedance data, and describe the combination as a three- degree-of-freedom system, consisting of three masses, interconnected by springs and dampers. The mass actually vibrating decreases as frequency increases because of low transmissibility at higher frequencies. Absorbed power was found to increase both along an equal sensation line and along the International Standards Organization tentative exposure hand-arm standards.
