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:

$$flang{e}_a.s=flang{e}_b.s$$

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

$$flang{e}_a.f=f$$

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

$$flang{e}_b.f=-flang{e}_a.f$$

This component extends from PartialRelativeSensor

Usage

ForceSensor()

Connectors

• flange_a - (Flange)

• flange_b - (Flange)

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