Abstract

We consider the cantilever beam model proposed in the seminal paper of Sader [1], where fluid damping effects on an oscillating cantilever are modeled. We show that in Sader's model, the transfer function of base-to-tip displacement fails to display high-frequency roll-off. It turns out that this is also true for the widely-used viscous damped beam model. We further demonstrate that the addition of Voigt damping to Sader's model creates the high frequency roll-off expected of a realistic model.
