Abstract
We consider the cantilever beam model proposed in the seminal paper of Sader, 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.
