The dynamic coupling of mechanical vibratory systems results in the oscillatory interaction between the bodies of the system as a whole, for a certain selection of some parameters the phenomenon of vibration absorption occurs, in this phenomenon the main system transfers its mechanical energy to the absorber, resulting in a minimum amplitude of movement of the primary system and the absorber develops a certain amplitude. In this work it is proposed to design a vibration absorber for a primary system that in turn is affected by the motion in the base, which produces vibrations, the motion in the base includes elastic and viscous actions. It has been possible to determine a set of parameters that allow the absorption of vibrations, likewise, the parameters determined not only allow the absorption, but also establish a transfer of the effect of the damping present in the base to the absorber.
