Tuned Mass Damper Passive Control of Aircraft Wings Vibrations

Resumo

In this paper we study passive control of aircraft wings vibrations using simple Tuned Mass Damper
(TMD). This kind of structures are prone to large amplitude oscillations excited by time varying lift and drag
forces, especially in turbulent conditions. These are low frequency vibrations, mainly in the first mode of vibration,
as the stiffness is also low due to large cantilever spans and small thickness. We propose to include a thin cantilever
metal bar inside the wing, carrying a point mass at its tip. This subsystem will be tunned so to be approximately
in resonance with the first wing vibration mode. Numerical modeling and simulation of the system, via the Finite
Element Method (FEM), will be performed to check the efficiency of this proposed Tuned Mass Damper.
