Dynamic characteristics of a flexible bladed-rotor with Coulomb damping due to tip-rub

TL;DR: In this article, a system of equations for a fully-bladed flexible rotor (shaft and disk) supported by a set of bearings at multiple locations is derived for hard rub with Coulomb friction.
Journal ArticleDOI

Natural frequencies of a pre-twisted blade in a centrifugal force field

TL;DR: In this paper, the authors derived the partial differential equation of motion for the transverse deflection of a rotating pre-twisted plate by considering it as a plate of an equivalent rectangular cross-section subjected to a quasi-static load due to a centrifugal force field.
Journal ArticleDOI

Rotordynamic analysis of asymmetric turbofan rotor due to fan blade-loss event with contact-impact rub loads

TL;DR: In this article, the effect of the rotary inertia and gyroscopic moments as a result of both shaft bending as well as staggered blades flexing in-and-out of the plane of the disk was investigated.
Journal ArticleDOI

Non-linear dynamic response of a rotating radial Timoshenko beam with periodic pulse loading at the free-end

TL;DR: In this paper, the dynamic response of a rotating radial cantilever Timoshenko beam clamped at the hub in a centrifugal force field was derived for coupled axial and lateral motions which included the transverse shear and rotary inertia effects, as well as the hyperbolic wave equation governing the axial motion is coupled with the flexural wave equations governing the lateral motion of the beam through the velocity-dependent skew-symmetric Coriolis force terms.
Journal ArticleDOI

Combined Torsional-Bending-Axial Dynamics of a Twisted Rotating Cantilever Timoshenko Beam With Contact-Impact Loads at the Free End

TL;DR: In this article, the dynamic response of a rotating cantilever twisted and inclined airfoil blade subjected to contact loads at the free end is considered. And the Rayleigh-Ritz method is used to convert the set of coupled partial differential equations into equivalent classical mass, stiffness, damping, and gyroscopic matrices.
