| Summary: | This paper presents the effect of foundation flexibility on the
optimum design of vibration absorbers. Flexibility of the base
is incorporated into the absorber system equations of motion
through an equivalent damping ratio and stiffness value in the
direction of motion at the connection point. The optimum
values of the uncoupled natural frequency and damping ratio
of the absorber are determined over a range of excitation
frequencies and the primary system damping ratio. Optimal
design parameters are computed and compared for the rigid,
and flexible models of the base as well as different levels of
base flexibility. |
