This paper deals with the effect of damping on the parametric combination resonances of viscoelastic systems subjected to a pulsating generalized Rent force. The effect of the direction factor of a generalized Rent force on the parametric resonances is investigated. The effect of an external and internal damping on the critical excitation parameter and the width of resonance regions is examined quantitatively.
