An Experimental Study on the Modal Test of Gas Turbine Blade Integrity

가스터빈 블레이드 MODAL TEST를 위한 실험적 방법에 관한 연구

In this paper, an experimental method of several modal analyses was devised to iify the vibration characteristics of G/T blade in power plants. Also, it is being applied this method to establish the standard category of natural frequency of new developed blades. So acceptance margin to avoid resonance due to nozzle waking force is being established for new blades. It is expected to improve the availability of G/T blades by using the result of this study.
