Purpose
Ideal rotational backlash

Description
The Rotational Backlash models an ideal symmetrical, two-sided Rotational Hard Stop in a rotational system, which restricts the relative displacement of the two flanges between an upper and lower limit of \(\pm \frac{b}{2}\). While the displacement is within the limits, no torque is transmitted. When the displacement hits either limit, the flanges become rigidly connected until the transmitted torque reverses.
Parameters
- Total backlash
The total permitted displacement \(b\) between the flanges, in radians.
- Initial displacement
The initial displacement of the flanges, in radians. May be specified in order to provide proper initial conditions if absolute angles are measured anywhere in the system. Otherwise, this parameter can be left blank.
Probe Signals
- Torque
The transmitted torque flowing from the unmarked to the marked flange, in newton-meters \((\mathrm{Nm})\).
- Displacement
The displacement of the marked flange with respect to the unmarked flange, in radians.
- State
The internal state of the component:
