Modelica.Mechanics.Rotational.Examples.Utilities.SpringDamperNoRelativeStatesLinear 1D rotational spring and damper in parallel (phi and w are not used as states)
A spring and damper element connected in parallel. The component can be connected either between two inertias/gears to describe the shaft elasticity and damping, or between an inertia/gear and the housing (component Fixed), to describe a coupling of the element with the housing via a spring/damper.
This is the same element as Rotational.Components.SpringDamper but with the only difference, that the relative quantities are not used as states. If the relative states are potentially used as states, "a_rel = der(w_rel)" is present, and then exporting this model as FMU requires to also have the accelerations in the flanges as inputs, which is usually not desired for a force element.
