| Abstract: | Focusing on the vibration abrasion problems of stator main lead for a 135MW air cooled turbo -generator, the vibration analysis and calculation in the structure of main lead was done with an advanced finite element method, and the real reasons caused vibration was found. Some concrete measures to stiffen and improve it were presented based on the vibration model obtained through calculation, the actual operation facts showed that these measures are suitable and effective, enabling to solve the vibration abrasion problems. |
