Analysis of Rotors in Bearings

  • E. Krämer
Part of the International Centre for Mechanical Sciences book series (CISM, volume 297)


This part begins with the main facts about the simplest rotor model, the Jeffcott rotor. A short comment follows about the approximate computation of the first critical speed. Then the start-up and shut-down behaviour of a rotor is described. The influence of bearings also is studied using the Jeffcott model. A simple model shows the influence of bearing damping. In the last section the main aspects of unbalance behaviour of multi-bearing systems are discussed.
