An Experimental Study on the Modal Test of Steam Turbine Shround Band

터빈 Shroud Band Modal Test에 관한 실험적 연구

We tested the natural frequency for the 1st moving blades of a steam turbine in general power plants, carried out the modal test of the blade groups each natural frequency. By this test results, we identified the resonance results largely in damaging the blades. We can predict damage probability for the blade groups and change state of material property by using the result of this study.
