This paper proposes a new method for design of damping in the roller pendulum system to be used for dynamic vibration absorber. Generally the shape of the roller using cylindrical, but in a proposed method using a regular polygonal prism. At first, damping characteristics of typical rigid polygonal prism is discussed theoretically. Next, natural frequency of roller pendulum is discussed theoretically. Finally, vibration characteristic of polygonal roller is confirmed by numerical calculation based on rigid multi-body dynamics.
