Rotating Force was added after Release 15. You will have to use APDL commands such as CORIOLIS and OMEGA to define angular velocity input to the rotating structure. Here is the section in the ANSYS 15.0 help
Here is a command object inserted with these commands
Here is the Freq. Response in Y with the command snippet. It is the same magnitude in Z.
Here is the Freq Response in Y without the Command Snippet. It is 1000 times smaller in Z.
You can create Force in the Y direction (assuming your shaft is along the X axis). It is sufficient to have a single unbalanced force since it is rotating.
Attached is the Release 15.0 model of an unbalanced shaft.
Alternatively, you could download ANSYS Student 19.2 and use Rotating Force.
