The excessive motion of dynamic vibration absorber is one of problems when it is applied to an actual system. If the excitation force increases, the mass of dynamic vibration absorber collides to the end of track. This shock response is undesirable to the system. In this study, we proposed a kind of two-step damping dynamic vibration absorber in order to reduce the shock. This dynamic vibration absorber is applied to the ropeway carrier which can be modelled as a pendulum. We used electro-magnetic force to realize the two-step damping dynamic absorber. This stepped-damping absorber reduces the shock when excitation force is large. When the excitation force is in a mid-range, the proposed dynamic absorber performs like the conventional dynamic absorber. Experiments of free vibration and forced vibration were conducted to show the usefulness of this mechanism.
