Vibration absorber is used to protect the primary system from steady-state harmonic disturbance. By attaching the absorber to the primary system which is modeled as a SDOF system, the new system becomes two DOF system as shown in the model below. Depending on the driving frequency on the original system, the absorber needs to be carefully tuned, that is, to cho0se adequate value of the absorber mass and stiffness, so that the motion of the original mass is a minimum.
