Centrifugal Loads
You can create a centrifugal load on the entire model resulting from rigid body rotation of the model in both native and FEM mode. You can specify the angular velocity and/or angular acceleration, which can have different vector directions. See Guidelines for Centrifugal Loads for more information.
When you define a centrifugal load, you specify to which load set it belongs. Note that you can have only one centrifugal load per load set.
When you click Home > Centrifugal, the Centrifugal Load dialog box opens with the following items:
Name—The name of the load.
Member of Set—The name of the load set. You can select an existing load set from the drop-down list, or create a new set by clicking the New button to display the Load Set Definition dialog box.
Coordinate System—Allows you to select the coordinate system that the centrifugal load will reference. You must select a Cartesian coordinate system.
Angular Velocity—Allows you to specify the direction and magnitude of the vector. The velocity can be positive or negative. For 2D axisymmetric models, you can only specify the magnitude of the angular velocity.
If you select the Dir Points & Mag option, see From and To Fields for Centrifugal Loads for more information.
Angular Acceleration—Allows you to specify the direction and magnitude of the vector. The angular acceleration vector is the rate of change of the angular velocity vector.
If you select the Dir Points & Mag option, see From and To Fields for Centrifugal Loads for more information.
Preview—Adds arrows to your model indicating the direction of the angular velocity and angular acceleration vectors. The tail end of the arrows are located at the instantaneous point of rotation. The angular velocity icon has one arrowhead, while the angular acceleration icon has two arrowheads, one on top of the other. If you specify angular velocity as 0, Creo Simulate displays only the angular acceleration arrow. Similarly, if you specify angular acceleration as 0, Creo Simulate displays only the angular velocity arrow.
After you complete the Centrifugal Load dialog box, the software places an angular velocity and/or angular acceleration load icon on the model. The icons represent vectors. The tail end of the vectors are located at the instantaneous point of rotation.
Centrifugal loads that are created for a part are not applicable at the assembly level. In the assembly they are displayed in the model tree with the icon—
Centrifugal load acts in the direction opposite to the direction of acceleration.
