Area of Science:

  • Biomechanics
  • Human-Computer Interaction
  • Ergonomics

Background:

  • The mechanical impedance of the human hand-arm system is crucial for understanding ergonomics and human-robot interaction.
  • This impedance is known to be significantly affected by grip force and the frequency of external stimuli.

Purpose of the Study:

  • To develop and validate biodynamic models of the human hand-arm system.
  • To characterize the influence of grip force on the system's mechanical impedance across a range of frequencies.
  • To compare the predictive accuracy of linear and nonlinear models.

Main Methods:

  • Characterization of hand-arm biodynamic response using three and four degree-of-freedom (DOF) linear and nonlinear models.
  • Incorporation of grip force dependence into the models' restoring and dissipative properties.

  • Model parameter identification via constrained optimization to minimize impedance magnitude and phase errors.
  • Measurement of target impedance in three orthogonal directions (Xh, Yh, Zh) from 10 to 1000 Hz using sinusoidal excitation (2g peak acceleration) and grip forces from 10 to 50 N.

    • Main Results:

    • Analysis of linear and nonlinear models to determine driving-point mechanical impedance characteristics at different grip force levels.
    • Validation of computed response characteristics against measured target values.
    • Demonstration that the four-DOF nonlinear grip force-dependent model shows strong correlation with measured responses across all three directions and tested grip forces.

    Conclusions:

    • The proposed four-DOF nonlinear model effectively captures the grip force-dependent biodynamic response of the human hand-arm system.
    • This model provides a more accurate representation compared to simpler linear models, especially within the tested frequency and grip force ranges.
    • The findings have implications for designing safer and more effective human-robot interfaces and ergonomic tools.
