Information

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

This package contains components that exert forces and torques between two frame connectors, e.g., between two parts.

Content

*Model*	*Description*
WorldForce	External force acting at the frame to which this component is connected and defined by 3 input signals, that are interpreted as one vector resolved in frame world, frame_b or frame_resolve.
WorldTorque	External torque acting at the frame to which this component is connected and defined by 3 input signals, that are interpreted as one vector resolved in frame world, frame_b or frame_resolve.
WorldForceAndTorque	External force and external torque acting at the frame to which this component is connected and defined by 3+3 input signals, that are interpreted as a force and as a torque vector resolved in frame world, frame_b or frame_resolve.
Force	Force acting between two frames defined by 3 input signals resolved in frame world, frame_a, frame_b or in frame_resolve.
Torque	Torque acting between two frames defined by 3 input signals resolved in frame world, frame_a, frame_b or in frame_resolve.
ForceAndTorque	Force and torque acting between two frames defined by 3+3 input signals resolved in frame world, frame_a, frame_b or in frame_resolve.
LineForceWithMass	General line force component with an optional point mass on the connection line. The force law can be defined by a component of Modelica.Mechanics.Translational
LineForceWithTwoMasses	General line force component with two optional point masses on the connection line. The force law can be defined by a component of Modelica.Mechanics.Translational
Spring	Linear translational spring with optional mass
Damper	Linear (velocity dependent) damper
SpringDamperParallel	Linear spring and damper in parallel connection
SpringDamperSeries	Linear spring and damper in series connection
