In this report, first, the forced vibrations of a circular plate with a nonlinear dynamic vibration absorber are investigated theoretically. The plate is simply supported at the outer edge subjected to a sinusoidal motion of constant amplitude. The restoring force of the nonlinear dynamic vibration absorber is represented by a hardening spring having both linear and cubic nonlinear bahavior. In the analysis, the one-third order subharmonic and the third order superharmonic vibrations as well as the fundamental one are assumed. Second, it is demonstrated that the optimal tuning and damping parameters for a nonlinear magnetic dynamic vibration absorber with a hardening spring can be easily found by using the simplex method.
