Forced response prediction for industrial gas turbine blades [PDF]

, 2006
A highly efficient aeromechanical forced response system is developed for predicting resonant forced vibration of turbomachinery blades with the capabilities of fully 3-D non-linear unsteady aerodynamics, 3-D finite element modal analysis and blade root ...

Experimental Investigation of Synchronous-Flow-Induced Blade Vibrations on a Radial Turbine

International Journal of Turbomachinery, Propulsion and Power
In this study, a thorough experimental investigation of the synchronous blade vibrations of a radial turbine is performed for different IGV configurations. First, the blade modes are measured experimentally and calculated numerically.

Measurement of the Period of Natural Vibration of an Airscrew Blade.

Measurement of the Period of Natural Vibration of an Airscrew Blade.
筆者等は最近プロペラのフラッターの研究に關聯してプロペラ翼の屈曲,捩り兩振動をおげ精密に測定する必要に會し,曩に航空研究所報告第103號に發表した三極眞空管を使用する方法を應用して良くその目的を達したが,其際此方法に種々改良,發展を行ひ,電氣濾波器,周波數分析器等を利用して好結果を得た.本篇は是等の實驗の報告である.
