| Abstract: | The calculation of critical speed of the large air-cooled turbine generator rotor is carried out by applying computer programs of the dynamic characteristics to see if it meets the design requirement of the lateral criteria. And then the modal analysis of rotor-bearing system is made by applying modal test to examine the validity of the calculation. The actual critical speed of the rotor is obtained by measuring. The data of the lateral dynamic characteristics of the air-cooled turbine generator's rotor are obtained in the round. |
