Use the Centrifugal PropertyManager to apply angular velocity and acceleration to a part or an assembly in static, frequency, buckling, or nonlinear studies. The software uses the specified values of angular velocity and acceleration and the mass density to calculate the centrifugal loads. For Nonlinear studies, you can define time-dependent angular velocity and acceleration.
To define centrifugal load to a model:
In the COSMOS AnalysisManager tree, right-click the Load/Restraint icon and select Centrifugal.
The Centrifugal PropertyManager appears.
In the graphics area, select an axis, an edge, or a cylindrical face to specify the direction of the centrifugal force.
The selected reference appears in the Axis, Edge, Cylindrical Face for Direction
box 
.
The centrifugal force is
always calculated with respect to an axis passing through the center of
gravity of the model and parallel to the selected direction.
Under Centrifugal Force, do the following:
Select the Units
you want to use to enter the values of the angular velocity
or acceleration. Available units are: radians, cycles,
and rpm (revolution per
minute).
Type a value for the Angular
Velocity 
. To reverse the direction of the angular
velocity, check Reverse direction.
Type a value for the Angular
Acceleration 
. To reverse the direction of the
angular acceleration, check Reverse direction.
In nonlinear studies, you can define time-dependent centrifugal forces by associating them with a time curve. Under Variation with time choose,
Linear. To use a default linear time curve which passes through the points (0,0) and (tend, A). Where A is the value of the angular velocity/angular acceleration specified in the Centrifugal Force box and tend is the End time specified on the Solution tab of the Nonlinear dialog box.
-or-
Curve. To use a user-defined time curve. Click Edit to define or import a time curve. The angular velocity/angular acceleration is calculated at any time by multiplying the value specified above by the Y value of the time curve.
Graph. Displays the actual time-dependent centrifugal force component(s).
