I have to retrieve the natural frequencies of an axis equipped with a disk.
I would like to know how to proceed to simulate an imbalance on the periphery of the disc and also recover the forces on the bearings.
Hello
Modeling a volume on the disk could represent the unbalance?
Or else by assigning a force with a single direction to a point on the outer diameter of the disc?
Hello
Yes, to simulate an imbalance, you have to draw it then:
Under External Loads, add a centrifugal load for rotational speed and direction. You can specify an acceleration if necessary. Also, try using a "remote load/mass" or a "distributed mass".
