Dynamic Characteristic Improvement for Journal Bearing Support of Power Plant Exciter considering Resonance

When the structure supporting the rotor as well as the rotor itself is in the resonant range, it cause the vibration problem. Although the static characteristics of structures was considered during the design process, we must consider the resonance problem between the excitation(the main revolution frequency of the rotor) between the dynamic characteristics of its structures. This paper presents we improved the dynamic characteristic of a bearing support system to remove a resonance problem so that stabilized the turbine-generator system.
