WebAug 7, 2024 · In a previous study, we proposed a method for the damping of rotationally periodic structures, when a specific mode with n nodal diameters is targeted. The proposed method considers 4n lead zirconate titanate patches (or a multiple of) which can be, either, shunted independently on 4n identical resistor–inductor circuits, or mounted in … WebJun 2, 2014 · The in-plane wave motion is analytically examined to address the stationary deflection, natural frequency splitting, and mode contamination of the rotationally ring-shaped periodic structures (RRPS). The governing equation is developed by the Hamilton's principle where the structure is modeled as a thin ring with equally-spaced …
