MultiSensor

Ideal sensor measuring absolute velocity, transmitted force, and power flow between two mechanical flanges.

This sensor measures key physical quantities between its two mechanical connection ports, flange_a and flange_b. It assumes an ideal connection where the positions of the flanges are identical (flange_a.s = flange_b.s). The component outputs:

• The absolute velocity v of flange_a, calculated as $v=\frac{d(flange\mathrm{\_}a.s)}{dt}$.

• The force f transmitted from flange_a to flange_b, taken as $f=flange\mathrm{\_}a.f$.

• The power power flowing from flange_a to flange_b, calculated as $power=f\cdot v$.

These quantities are made available as real output signals for monitoring or control purposes.
