Behavior of a dynamic vibration absorber system with viscous damping in the main system and coulomb friction combined with viscous damping in the absorber is investigated. In this case, the main mass is excited by a rotating unbalance, whose amplitude is proportional to the square of its angular frequency. The solution for the non-stop steady state motion is deduced from the equation of motion refering to the half cycle of relative motion by means of the same boundary condition method as the previous paper^<(2)>. Some results are confirmed through the simulation by digital computer with good coincidence. And it becomes clear that the Coulomb friction in the absorber does not work effectively to control the main mass vibration. The optimum tuning and damping of the system may be known from the newly proposed empirical formulae.
