內容簡介:

氣動彈性力學屬於流固耦合範疇,是一門包含氣體動力學和彈性力學的交叉學科。流固氣彈耦合表現為固體的振動,對於航空發動機的壓氣機和渦輪葉片而言,它會引起葉片的高周疲勞。這關係到葉片的壽命,壓氣機/渦輪的安全運行等問題,所以對氣彈問題進行研究顯得至關重要。杜克大學高級研究科學家Kielb將從渦輪葉片的顫振基本原理,失諧壓氣機葉片的強迫響應,非同步振動和低壓渦輪葉片顫振,分四個報告給以詳細介紹。

Introduction:

 Aeroelasticity belonging to the category of fluid-structure coupling problem involves multi-disciplines, such as aerodynamics and elastics. Fluid-structure aeroelastic coupling leads to structural vibration. In the context of compressors and turbines of aero-engines, the vibration is of high cycle nature and can lead to high-cycle fatigue which adversely affects blade’s life and safe operation of compressors/turbines. Therefore, turbomachinery aeroelasticity is a vitally important subject. Prof. Kielb will lecture on turbomachinery aeroelasticity through four talks: fundamentals of turbine blade flutter, forced response of mistuned compressor blades, nonsynchronous vibration and low pressure turbine blade flutter.
