Hello
I'm looking for information about stiffness modeling of the rotor in the area of large diameter changes.
The rotor model I am using is diveded in elements and every element is defined with its iner/outer mass and stiffness diameters. The mass diameters follow the contour of the rotor and...
There are two different cases:
The first is when the rotor is radially shifted constantly. This gives an excitation force acting with twice the rotating frequency. However in reality the misalignment is so small, that this force can be neglected. (???)
The second case is more complicated. Due...
