Numerical modelling of the aeroelastic response of irregular slender structures

Nguyen, CH

Abstract

This paper presents a general framework for the evaluation of the aeroelastic response of a complex slender structure with generic cross sections. First, the Rayleigh–Ritz approach and the Lagrange equation are employed to describe the vibrations of a continuous coupled structure through a system of ordinary differential equations in common forms which are familiar to structural analysts. Then, the general framework for instability analysis will be presented. Finally, the theory is then applied to a real telecommunication pole with an irregular shape. The numerical results show different aspects from traditional findings, emphasizing the structural irregularity.
