Beschreibung
Dieser Befehl wendet eine Kraft mit dem gegebenen Wert [N] auf die ausgewählte Zielgeometrie an.
Anwendung
1) Applying a force in normal direction to a face
- If you have Mesh displayed, you need to hide it (select the mesh object and press spacebar or right click and select Hide item) and show the original model.
- Click on a face to which a force should be applied. It will appear in the list of geometrical objects.
- Fill in Line load with a force value in [N] (attention: Not in [N/m])
- Direction: In a typical case, you'll click this field empty to apply a force in normal direction to the face. You can revert the direction of the force by clicking Reverse direction. In other cases, you need to pick a face or plane, which is in normal to the force direction (it could differ from the face, to which the force is being applied)
- Click Close to finish the dialog and create ConstraintForce object
2) Applying a force in to line in selected direction
- In FEM workbench, click on or select Model → Mechanical Constraints → Constraint force to open Force Constraint properties dialog
- If you have Mesh displayed, you need to hide it (select the mesh object and press spacebar or right click and select Hide item) and show the original model.
- Click on a line segment to which a force should be applied. It will appear in the list of geometrical objects.
- Fill in Area load with a force value in [N]
- Direction: Now, with line segment selected, it si likely that the force is applied in a wrong direction. We need to specify the direction by clicking the button Direction and then clicking a face pointing with its normal to the direction of the force (or reversed direction). Again, you can revert the direction of the force by clicking Reverse direction.
