This paper presents a numerical study of a nonlinear two-degrees-of-freedom system consisting of the Duffing oscillator with an attached pendulum absorber. The system is excited close to the principal parametric resonance. By applying numerical simulation we show the influence of viscous and a magnetorheological damping (MR) on the vibration absorption effect. The absorber can be highly efficient for slightly damped systems, if it is correctly tuned. A new element in this work is to use the MR damper, modelled with the effect of hysteretic loop in the nonlinear damper.
