Commercial Space Station Activities,ative effects like oil film forces, forces in seals etc. It is important to know that besides the forced unbalance vibrations also unstable vibrations may occur, caused by the abovementioned selfexciting mechanisms /1/. To have a better understanding of the vibration behavior of rotating systems, th
