Description
The Torsion Spring models an ideal linear spring in a rotational system described with the following equations:



Note An torsion spring may not be connected in series with a torque source. Doing so would create a dependency between an input variable (the source torque) and a state variable (the spring torque) in the underlying state-space equations.
Parameters
- Spring constant
- The spring rate or stiffness
, in

- Equilibrium (unstretched) displacement
- The displacement
between the two flanges of the unloaded spring, in radians.
- Initial deformation
- The initial deformation (torsion)
of the spring, in radians.
