Damper

Linear 1D rotational damper

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Linear, velocity dependent damper element. It can be either connected between an inertia or gear and the housing (component Fixed), or between two inertia/gear elements.

See also the discussion State Selection in the User's Guide of the Rotational library.
