Angular velocity (ω) defines the speed of rotation of the entire model and the axis
about which it rotates. Angular acceleration (α) is the rate of change of the model's
angular velocity.
You can apply one or both to a specific point on the model using the Apply Angular
Velocity and Acceleration tool.
Apply Angular Velocity and Acceleration
On the Structure ribbon, select the Angular Velocity and
Acceleration tool.
Click on the model to apply angular velocity/acceleration.
To apply angular velocity, select the ω checkbox and
enter a value.
To apply angular acceleration, select the α checkbox and
enter a value.
Right-click and mouse through the check mark to exit, or double-right-click.
Tip:
Angular velocity can be specified in rad/sec, rpm, or rps; angular
acceleration in rad/sec2 or rev/sec2.
Each point where angular velocity/acceleration is applied is called a
rotation in the Model Browser and is represented as a curved rotational
arrow in the modeling window.
Rotations are specific to a load case, but are applied to all parts in an
analysis or optimization. Generally, you would only have one per load
case.
Use the right-click context menu to include or exclude angular
velocity/acceleration from a load case.
Microdialog Options
Select the ω checkbox to enable angular velocity and enter a value.
Select the α checkbox to enable angular acceleration and enter a value.
Translate or rotate the rotational axis using the Move tool.
Align the rotational axis to the X, Y, or Z axis. Repeated clicks reverse the
direction.
Click to orient the rotational axis by entering component vectors for x, y, and
z. (For example, entering 1, 0, 0 would orient it in the positive x
direction.)
