SpringDamper

Linear 1D rotational spring and damper in parallel

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 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.
