| Abstract: | According to the vibration spectrum of some marine turbine-generator set, this paper analyzed why the set would vibrate. The results of analyses show that sliding bearings of the turbine-generator are easily influenced by the boundary conditions. Among these reasons, the shaft alignment change is one of the key reasons for disturbing these sliding bearings. |
