BasicWorldTorque
External torque acting at frame_b, defined by 3 input signals
Library
Modelica/Mechanics/MultiBody/Forces/Internal
Description
The 3 signals of the torque connector are interpretedas the x-, y- and z-coordinates of a torque acting at the frameconnector to which this component is attached.Via parameter resolveInFrame it is defined, in which frame thesecoordinates shall be resolved:
Types.ResolveInFrameB. | Meaning |
---|---|
world | Resolve input torque in world frame (= default) |
frame_b | Resolve input torque in frame_b |
frame_resolve | Resolve input torque in frame_resolve (frame_resolve must be connected) |
If resolveInFrame = Types.ResolveInFrameB.frame_resolve, the torque coordinatesare with respect to the frame, that is connected to frame_resolve.
If resolveInFrame is not Types.ResolveInFrameB.frame_resolve, then the positionvector and the orientation object of frame_resolve must be set to constantvalues from the outside in order that the model remains balanced(these constant values are ignored).
