| Abstract: | The fault of a 600MW turbine generator unit occurred in operation such as the collision and friction between the rotating rotor and the fixed oil baffle ring and the various over- proof shaft vibration amplitude. Based on the analysis of accident, the internal and external causes were founded out, i.e. the bad processing form stress concentration and then lead to craze and crack. This paper can provide reference to avoid the similar accidents. |
