Vibrations and Elements of Aeroelasticity

About the Subject:

Aero elasticity is the branch of physics and engineering that studies the interactions between the inertial, elastic, and aerodynamic forces that occur when an elastic body is exposed to a fluid flow. Although historical studies have been focused on aeronautical applications, recent research has found applications in fields such as energy harvesting and understanding snoring. The study of aero elasticity may be broadly classified into two fields: static aero elasticity, which deals with the static or steady response of an elastic body to a fluid flow; and dynamic aero elasticity, which deals with the body’s dynamic (typically vibration) response. Aero elasticity draws on the study of fluid mechanics, solid mechanics, structural dynamics and dynamical systems. The synthesis of aero elasticity with thermodynamics is known as aerothermoelasticity, and its synthesis with control theory is known as aeroservoelasticity.

Topics to be covered in this Seminar:

Single degree of freedom systems– damped vibrations – forced vibrations, with and without damping – support excitation – transmissibility - vibration measuring instruments. Multi degrees of freedom systems- static and dynamic couplings - vibration absorber- principal co-ordinates - principal modes and orthogonal conditions - Eigen value problems - Hamilton’s principle - lagrangean equations and application.  Continuous systems - Vibration of elastic bodies -  Approximate methods- Rayleigh’s method - dunker lays method – Rayleigh - ritz method, matrix iteration method.
