Area of Science:

  • Biomechanics
  • Robotics
  • Human-Computer Interaction

Context:

  • Pathological tremor in the human upper limb significantly impacts daily activities.
  • Accurate characterization of tremor dynamics is crucial for developing effective suppression strategies.

Purpose:

  • To develop and validate a simulation system for pathological human arm tremor.
  • To analyze the dynamic response characteristics of pathological tremors.

Summary:

  • A two-degree-of-freedom human arm dynamic model was established and linearized.
  • Analytical and numerical solutions were used to determine natural frequencies (2.9 Hz and 5.4 Hz).
  • A simulation system was built using measured human arm parameters, validating the theoretical model through experimental results.

Impact:

  • The developed system accurately characterizes pathological tremor frequency and amplitude.
  • Provides a theoretical foundation and experimental basis for wearable tremor suppression devices.
