Optimization of vibration characteristics and directional propagation of plane waves in branching ligament structures of wind models

To achieve multi-frequency vibration suppression and wave propagation modulation, eight branching ligament structures for wind models are proposed. Using lattice theory, dynamical model and finite element release method, the structures are verified to have multi-frequency bandgaps. By attaching a so...
