Abstract

In
this study, forced vibration of a rotating disk is investigated. The disk is
clamped at the inner and free at the outer circumferences. A time varying excitation
force is applied to a spacefixed point on the disk surface perpendicularly. The
presence of multiple excitation forces is also considered in the paper. These
forces can be applied to any spacefixed point on the disk surface. The disk is
modelled as a thin plate and the Galerkin method is used to analyze the forced
vibration characteristics of the rotating disk. Power spectral density diagrams
of the forced vibrations with both one and multiple excitation forces are
plotted.
