Damping by branching
WebA new damping mechanism inspired by the architecture of trees is here identified and characterized in the simplest tree-like structure, a Y-shape branched structure. Through … WebAug 1, 2024 · The vibration frequency still shows the three different trends that occur in the three branches at low damping. In the upper branch of the low damping case, the normalized vibration frequency increases with U ∗ but no longer overlaps with the St = 0.208 line, and a third harmonic of the fundamental frequency appears in the lift force. These ...
