Coupling Simulation Algorithm of Discrete Element Method and Finite Element Method for Particle Damper

摘要

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