Coupling simulation algorithm of discrete element method and finite element method for particle damper

Abstract

One advantage of the particle damper is that its property is independent of the surrounding temperature. This allows it to be used in harsh environments where traditional dampers fail. But current design of this damper mainly depends on experimental results because of a lack of theoretical research. In this paper, an investigation into particle dampers is performed analytically and experimentally. A coupling simulation algorithm based on the discrete element method and finite element method is presented. Comparison between the analytical and experimental results shows that simulation of the response of a cantilever plate with a particle damper is accurate. It is shown that the response of the cantilever plate depends on the mass-fill ratio and particle density of the particle damper.
