Behavior of a dynamic vibration absorber system with combined viscous and Coulomb friction both in the main system and in the absorber is investigated. In this case, the main mass is excited by a rotating imbalance and the amplitude of the disturbing force varies as the square of its frequency. The solution of non-stop steady motion is deduced by means of the same boundary condition method as in the previous report. The numerical results of analytical solution coincide very well with those of digital simulation. A set of empirical formulae for calculating the oputimum tuning and damping of the absorber, constructed by composing the formulae given in the previous reports and adding some correction terms, are presented.
