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

ModelDescription
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.
