Flutter analysis of Stonecutters Bridge

Wind and Structures, 2006
Stonecutters Bridge of Hong Kong is a cable-stayed bridge with two single-column pylons each 298 m high and an aerodynamic twin deck. The total length of the bridge is 1596 m with a main span of 1018 m. The top 118 m of the tower will comprise structural steel and concrete composite while the bottom part will be of reinforced concrete.

Nonlinear analysis of flutter

2008
Flutter is an aerolastic phenomenon that makes structures oscillate when surrounded by a moving fluidum. Flutter can lead to fatigue and/or failure on the wings, flaps and fuselage of an airplane. Laborious testing needs to be done on aircraft to ensure safe operation within a certain flight envelope.

Flutter analysis of light aircraft

Acta Mechanica, 1986
The paper presents a method of flutter analysis of aircraft. It is assumed that the aircraft structure is linear-elastic. Displacements of the structure are approximated by superposition of ''rigid modes'' and natural vibration modes. The method of ''harmonic balance'' is applied to nonlinear control systems.

Flutter Analysis Using Quasi-Steady Time-Domain Flutter Derivatives

IABSE Reports, 2019
<p>To be able to perform nonlinear flutter analyses for bridges, time‐domain approaches should be used instead of Scanlan’s formulation of self‐excited forces. Thus, this paper addresses the development and validation of a modified quasi‐steady time‐domain model similar to Scanlan’s approach that is based on the velocity and acceleration of the ...

Flutter Analysis of Viscoelastic Panels in Supersonic Flow

Advanced Materials Research, 2012
In this paper, dynamic instability behavior of a linear viscoelastic panel in supersonic flow is investigated. The quasi-steady piston theory of supersonic flow is employed for the aerodynamic pressure. The partial differential governing equation of isotropic flat panel is derived by introducing viscoelastic structural damping based on Kelvins model ...

Finite element analysis of Supersonic panel flutter

International Journal for Numerical Methods in Engineering, 1973
INTRODUCTION The finite element method is a powerful tool to solve static and dynamic problems of structural analysis. Its application to flutter analysis can be envisaged in two ways. It can be used to obtain a more accurate modal shape of complex structures which in turn are introduced in traditional methods.

Cascade Flutter Analysis of Cantilevered Blades

Journal of Engineering for Gas Turbines and Power, 1984
An analysis has been developed to treat the aeroelastic behavior of a cascade of cantilevered blades. The unique features of the formulation include consideration of (a) coupling between bending and torsion in each of the blade modes, (b) coupling among blade modes, (c) spanwise variation of blade mode shapes, (d) mechanical damping in each mode, (e ...

Flutter Analysis of Circular Panels

Journal of the Aerospace Sciences, 1962
Summary The flutter problem of flat circular panels with edges elastically restrained against rotation has been formulated in terms of smalldeflection plate theory. The panel is subjected to uniform allround tension or compression in its middle plane, in addition to the supersonic compressible flow passing over its upper surface with still air below ...

Aeroelasticity analysis of aircraft wings in flutter-onset or post-flutter regime

2007
Because the flutter phenomenon is usually associated with large deformations/deflections, the structural solution based on linear theory gives inaccurate or totally unphysical solution because the equilibrium of the structure is referred to the initial state of the structure.
