Package with models that are used to construct the models in package Forces. The models in this package should not be directly used by a user.
Extends from Modelica.Icons.InternalPackage (Icon for an internal package (indicating that the package should not be directly utilized by user)).
| Name | Description |
|---|---|
BasicForce | Force acting between two frames, defined by 3 input signals |
BasicTorque | Torque acting between two frames, defined by 3 input signals |
BasicWorldForce | External force acting at frame_b, defined by 3 input signals |
BasicWorldTorque | External torque acting at frame_b, defined by 3 input signals |
standardGravityAcceleration | Standard gravity fields (no/parallel/point field) |
The 3 signals of the force connector are interpreted as the x-, y- and z-coordinates of a force acting at the frame connector to which frame_b of this component is attached. Via parameter resolveInFrame it is defined, in which frame these coordinates shall be resolved:
| Types.ResolveInFrameAB. | Meaning |
|---|---|
| world | Resolve input force in world frame |
| frame_a | Resolve input force in frame_a |
| frame_b | Resolve input force in frame_b (= default) |
| frame_resolve | Resolve input force in frame_resolve (frame_resolve must be connected) |
If resolveInFrame = ResolveInFrameAB.frame_resolve, the force coordinates are with respect to the frame, that is connected to frame_resolve.
If resolveInFrame is not ResolveInFrameAB.frame_resolve, then the position vector and the orientation object of frame_resolve must be set to constant values from the outside in order that the model remains balanced (these constant values are ignored).
