Working frequency
Short definition
The eccentric rotation frequency of the operating mode, set in the vibro profile (10–200 Hz); a green marker on the sweep chart.
Full definition
f_work is the VibrationProfile.freq_hz operating point; scalar KPIs (grip amplitude, dynamic hand force, ISO check) are evaluated there, while curves are computed by the 10–200 Hz sweep. It is chosen away from resonances and, preferably, inside the 18–33 Hz physiological band.
Examples
f_work = 25 Hz: D(r) ≈ 1.27 — near quasi-static.
