Simulation-Based Development and Experimental Validation of Tool-Integrated Rotary Particle Dampers

The primary focus lies on a comparative assessment between conventionally designed particle dampers and damper configurations incorporating integrated internal structures, fabricated via Laser Powder Bed Fusion (LPBF).

The recordings distinctly reveal the inhomogeneous particle distribution arising within the cavity segments in the absence of an internal structure, and demonstrate its effective suppression through the implementation of an integrated lattice structure. Moreover, the recordings document the kinematic behavior of additively manufactured spherical elements within the lattice structure. By constraining particle motion to a defined range commensurate with the respective particle dimensions, the lattice structure facilitates controlled particle dynamics while precluding chaotic inhomogeneities.
