The nonlinear damping behavior of particle dampers and the multitude of influence parameters hinder their wide industrial usage. Hence, the goal of this work is the development of a new design methodology in form of a toolchain enabling a systematic damper design. On that account, various numerical models and experimental tests are combined. The toolchain commences with investigations of the micro-mechanical behavior of single particle impacts, continues with analyzing the properties of vibrating granular matter inside different containers and ends with designing a particle damper for a desired vibrating structure. The good agreement of the experimental and numerical models and their efficiency for the damper design and dimensioning are demonstrated on multiple examples.
