Abstract
In this research paper, we study on how to decrease the high vibration of turbine hood casings which are main facilities of power generation industry. Cause of Standard coal-fired power 500MW facilities turbine hoods' high vibration is that Natural frequency of hood casing designed in near domain frequency, when they are making hoods. We investigate to reduce high vibration at hood casing. We use FEM method to found how to avoid resonance, and test to confirm that our FEM result. We Finally attach minium mass plate at hood casing to avoid resonance and high vibration reduce lower $100{\mu}m$.
