Centrifugal Load—Generative Design
Centrifugal loads are body loads that simulate rigid body rotation for your model. When you define a centrifugal load you specify either the vector components of angular velocity, or the direction vector and magnitude. The resulting body load acts in the direction opposite to the direction of centripetal and tangential velocity.
To Define a Centrifugal Load
1. Click Loads > Centrifugal. The Centrifugal Load dialog box opens.
2. Specify a name for the load, or use the default name. Optionally click the color swatch adjacent to the Name box to change the color of the icon, the distribution, or the text displayed for the load.
3. The default coordinate system of the model is the reference coordinate system and is displayed in the Coordinate system collector. If the model does not have a default coordinate system then the button is not available and the Coordinate system collector is empty. You can select any coordinate system, or create a UCS (user coordinate system).and designate it as the default coordinate system.
You can also select an alternative reference coordinate system from the Model Tree or Graphics Window.
Click to return to using the default coordinate system of the model.
4. Select one of the following options to define the magnitude and direction of angular velocity:
Magnitude and direction—Specify the value of the unit vectors for direction by typing a value of 0, 1, or -1 in the X, Y, or Z field.
Alternatively click and select a linear edge or planar surface in the model to specify the direction of angular velocity. The value of the unit vector is displayed in the X, Y, or Z field.
Specify the magnitude of angular velocity in the Magnitude box.
Directional components—Specify the components of angular velocity for each coordinate direction X, Y, or Z. The resultant direction and magnitude of velocity is determined from the values you specify for each coordinate. If you enter a positive value the velocity is applied in the same direction as the vector. If you use a negative value, the direction of velocity opposes the vector.
5. Select units of angular velocity from the list or accept the default units.
6. Click OK to create the load and save it.
