✦ Synopsis

The aim of this paper is to determine whether one dynamic absorber can reduce the amplitude of the steady state vibration of a parametric system for natural and parametric resonance frequencies simultaneously. The e$ciency of both the conventional dynamic absorber and the parametric absorber is analyzed. The "rst order sensitivity analysis of parametric periodic systems in the time domain is applied to obtain logarithmic sensitivity functions in the frequency domain. The "rst order sensitivity logarithmic functions are used to tune the conventional absorber and the parametric absorber.
