Study on Tuned Rotary-Mass Damper using Polygonal Slope

Abstract

In this paper, authors proposed a new method to add damping to Tuned Rotary-Mass Damper(TRMD). New TRMD developed by the authors uses a cylindrical mass and a polygonal slope for adding to damping characteristics.by inelastic collision. And this new method will realize adding damping characteristics at low cost, because the damping coefficient can be designed by the number of sides of the polygonal slope.
