Wavelet Transform-Based Damage Identification in Bladed Disks and Rotating Blades [PDF]
Shock and Vibration, 2018 Blade vibration and blade clearance are effective diagnostic features for the identification of blade damage in rotating machines. Blade tip-timing (BTT) is a noncontact method that is often used to monitor the vibration and clearance of blades in a ...

Rotating Flows Driven by Axisymmetric Blades in a Cylinder
International Journal of Rotating Machinery, 1999 A study is made of steady state flow of a viscous fluid, driven by a rotating endwall disk having radial blades in a finite geometry. Numerical solutions to the Navier-Stokes equations are obtained for the flows in the cylindrical cavity.

Blade dynamic stress analysis of rotating bladed disks [PDF]
Applied and Computational Mechanics, 2007 The paper deals with mathematical modelling of steady forced bladed disk vibrations and with dynamic stress calculation of the blades. The blades are considered as 1D kontinuum elastic coupled with three-dimensional elastic disk centrally clamped into ...

Vibrations of Twisted Rotating Blades
Journal of Vibration and Acoustics, 1984 The literature dealing with vibrations of turbomachinery blades is voluminous, but the vast majority of it treats the blades as beams. In a previous paper a two-dimensional analytical procedure was developed and demonstrated on simple models of blades having camber.

Effect of the Mechanical and Thermal Stresses of Rotating Blades [PDF]
Al-Khawarizmi Engineering Journal, 2007 Rotating blades are the important parts in gas turbines. Hence, an accurate mathematical estimation (F.E.M) of the stresses and deformations characteristics was required in the design applications to avoid failure.

Linearization of friction effects in vibration of two rotating blades
Applied and Computational Mechanics, 2013 This paper is aimed at modelling of friction effects in blade shrouding which are realized by means of friction elements placed between blades. In order to develop a methodology of modelling, two blades with one friction element in between are considered

On The Vibration of a Cracked Rotating Blade [PDF]
Shock and Vibration, 1998 The dynamic behavior of a rotating blade containing a transverse crack was investigated. First, the local flexibility of the cracked blade was obtained by using the method of the released energy. An energy principle, in conjunction with a weighted residual method, was then applied to yield the discrete equations of motion.
