Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
A spring and damper element connected in parallel. The component can be connected either between two masses to describe the joint elasticity and damping, or between a mass 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 Translational.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(v_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.
