Point Load
Use a Point Load node to apply point load on the rotor.
Frame Type
Select a Frame type — Spatial or Corotating to specify the load in the appropriate frame.
•
Since the beam rotor is modeled in the spatial frame, a stationary load in a Corotating frame works as a rotating load in the model. This load changes its direction with the angular velocity of the rotor. A stationary load in the Spatial frame is a true static load for beam rotor.
•
For a frequency-domain analysis, load in the Corotating frame is phase shifted to give the effect of rotation.
•
For a stationary analysis, Frame type has no influence on the analysis.
Force
Select the Load type — Force per point or Total force. Then enter values or expressions based on the selection of the point load FP or total force Ftot.
The Load list normally only contains User defined. When combined with another physics interface that can provide this type of load, it is also possible to choose a predefined load from this list.
Moment
Select the Moment type — Moment per point or Total moment. Then enter values or expressions based on the selection of the point moment MP or total moment Mtot. The given moment is applied to each of the selected points.
•
You can add the Phase subnode to specify the phase of this load in a frequency-domain analysis.
