Description
The Controlled Translational Friction component models the friction between two flanges in a translational system. It maintains zero relative velocity between the flanges up to the limit of the breakaway force \(F_{\mathrm{brk}}\). When the breakaway force is exceeded, the flanges slide against each other and the component generates the Coulomb friction force \(F_{\mathrm{C}}\).
This component does not include viscous friction.
The breakaway force \(F_{\mathrm{brk}}\) is determined by the control signal and must always be greater than or equal to zero. The magnitude of the Coulomb friction \(F_{\mathrm{C}}\) is proportional to the control signal.
Parameters
- Relative Coulomb friction force
The coefficient \(c_C\) determines the magnitude of the Coulomb friction force \(F_{\mathrm{C}}=c_C \cdot F_{\mathrm{brk}}\) and must be between zero and one.
Probe Signals
- Force
The transmitted force \(F\) flowing from the unmarked to the marked flange, in newtons \((\mathrm{N})\).
- Speed
The speed \(v\) of the marked flange with respect to the unmarked flange, in \(\left( \frac{\mathrm{m}}{\mathrm{s}} \right)\).
- State
The internal state of the component:
-1sliding backward,0stuck,+1sliding forward.
