Design Rules for Laser Beam Melted Particle Dampers

Abstract By means of additive manufacturing, especially laser powder bed fusion, particle dampers can be integrated locally into structural components and thus significantly reduce component vibrations. However, detailed design recommendations for additively manufactured do not yet exist. The research question in this paper is: How the effect damping described as a function excitation force, cavity width length? For beams made AlSi10Mg, it is shown that powder-filled 2.5% to 5% sufficient increase by more than x10.
