Uncertainties in damping estimates can significantly affect the dynamic response of a given flexible structure.
A common practice in linear structural dynamics is to consider a linear viscous damping model as the major energy dissipation mechanism.
However, it is well known that different forms of energy dissipation can affect the structure's dynamic response.
The major goal of this paper is to address the effects of the turbulent frictional damping force, also known as drag force on the dynamic behavior of a typical flexible structure composed of a slender cantilever beam carrying a lumped-mass on the tip.
First, the system's analytical equation is obtained and solved by employing a perturbation technique.
The solution process considers variations of the drag force coefficient and its effects on the system's response.
Then, experimental results are presented to demonstrate the effects of the nonlinear quadratic damping due to the turbulent frictional force on the system's dynamic response.
In particular, the effects of the quadratic damping on the frequency-response and amplitude-response curves are investigated.
Numerically simulated as well as experimental results indicate that variations on the drag force coefficient significantly alter the dynamics of the structure under investigation.
