摘要
En 中文
Vibration mode localization in disordered cyclic structures is studied. The equations of motion of a wrap-rib antenna are formulated. Only a single substructure mode is taken for each rib. The localization factors which characterize the exponential rates at which the vibration amplitudes grow (decay) are determined by two approaches. The first approach uses a transfer matrix formulation and Furstenberg's theorem on asymptotic properties of products of random matrices. The second method employs a Green function formulation.
