ForceSensor ​

Ideal sensor measuring the translational force transmitted between two flanges.

This component models an ideal sensor that measures the translational force acting between its two mechanical flanges, flange_a and flange_b. It ensures the sensor body is perfectly rigid, meaning no relative displacement between the flanges. This is expressed by the equation:

flangea.s=flangeb.s

The force exerted at flange_a is directly measured and provided as the output signal f:

flangea.f=f

By Newton's third law, the force at flange_b is equal and opposite to the force at flange_a:

flangeb.f=−flangea.f

PartialRelativeSensor

Usage ​

ForceSensor()

Connectors ​

  • flange_a - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)

  • flange_b - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)

  • f - This connector represents a real signal as an output from a component (RealOutput)
