Collision-friction vibration failure diagnosis of shipping steam-generator with acoustic emission testing technique |
| |
| Abstract: | Collision-friction vibration is the most familiar failure of shipping steam-generators. On the basis oi analysis to the principle of collision-friction vibration and characteristic comparison between the vibration test and acoustic emission test, a comprehensive analysis method to diagnose the collision-friction vibration failure of steamgenerator with acoustic emission testing technique is brought forward and its applicability is proved. |
