Vibration of a Clamped Circular Plate Driven by a Noncentral Force.
Abstract
Expressions are stated for the transmissibility and for the driving-point impedance of an internally damped circular plate of radius a with a clamped boundary that is driven by a vibratory point force at an arbitrary distance micron from the plate center. Expressions are also stated for the plate transmissibility when the plate is loaded at the arbitrary driving point either by a lumped mass, by a dynamic vibration absorber--or, simultaneously, by a lumped mass and a dynamic absorber. In all cases, representative calculations of transmissibility are plotted versus the square root of frequency. These curves clearly show the dependence of transmissibility and impedance on the plate damping factor, the value of the parameter mu, and the extent of the mass loading. They also show the effectiveness of the dynamic absorber, which varies with the value assigned to mu. (Author)
