It would help to have a coordinate triad so we can refer to directions. I will assume that the disk is in the X-Y plane and rotates about the Z axis.

Create 3 Static Structural analyses.

The first analysis computes the effect of the angular velocity. Assign a Rotational Velocity using the maximum angular velocity the disk will achieve. (Omega)

The second analysis has a Standard Earth Gravity in the X axis (1G-X)

The third analysis has a Standard Earth Gravity in the Y axis (1G-Y)

Use a Solution Combination where alpha is the angle of rotation to add sine(alpha)*1G-X and cosine(alpha)*1G-Y and add the Omega solution. You might want to create 24 rows of Solution combinations to capture the effect of gravity in 15 degree increments.
