Mistuning이 블레이드의 진동특성에 미치는 영향

In turbine machine, there are small differences in the structural and/or geometrical properties of individual blade, which are referred to as blade mistuning. Mistuning effects of the forced response of bladed can be extremely large as often reported in many studies. Wind turbine is occurred by vibration from blade and other problem, too. SO in this paper, mistuning is considered at wind turbine blade for decreasing vibration. The wind turbine blade are analyzed by the MSC/NASTRAN to identify the vibration characteristic for mistuning. Mistuning according analysis results is performed.
