This International Standard specifies the mechanical impedance of the human male hand-arm system at the driving point. Values of the impedance, expressed as modulus and phase, are provided for three orthogonal, translatory directions of excitation that correspond to the xh-, yh– and zh-axes of the basicentric coordinate system.
NOTE 1 The basicentric coordinate system is defined in ISO 5349-1[2] and ISO 8727.[5]
The xh-, yh– and zh-components of impedance are defined as a function of frequency, from 10 Hz to 500 Hz, for specified arm positions, grip and feed forces, handle diameters, and intensities of excitation. The components of impedance in the three directions are treated as being independent.
This International Standard can be used to define typical values of the mechanical impedance of the hand-arm system at the driving point, applicable to males under the circumstances specified. This International Standard can provisionally be applied to females.
Reference values of the mechanical impedance at the driving point are provided as a function of frequency for a specified grip and feed force.
NOTE 2 See Annex A.
These impedance values are intended for the determination of the transmissibility of resilient materials when loaded by the hand-arm system.
Mathematical representations of the hand-arm system that model the mean values of apparent mass or impedance are provided.
NOTE 3 See Annexes B to D.
A gloved hand-arm model is described, and the frequency dependence of vibration power absorption in the hand-arm system is also provided.
NOTE 4 See Annexes E and F.
To help conduct further measurement of the mechanical impedance, especially for circumstances that are not specified in this International Standard, information on the measurement of mechanical impedance is provided.
NOTE 5 See Annex G.
