SpringDamper

Linear 1D translational 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 sliding masses to describe the elasticity and damping, or between a sliding mass and the housing (model Fixed), to describe a coupling of the sliding mass with the housing via a spring/damper.
