This paper is concerned with the problem of keeping the pantograph in contact with the overhead-line on a railway. A new system of wire and pantographs was proposed to which a dynamic damper was added in order to avoid sparking on the contact wire. The phenomenon of the system was analyzed and the effects by dynamic damper were were examined. Consequently it was demonstrated in the present paper that the natural frequency of the auxiliary equipment affects considerably the rate of the amplitude growth in the unstable region, and the best tuning condition for resonance lowers greatly the static amplitude in parametric excitation if the dynamic damper has a viscous damping element
