文摘

A macro-mechanical cantilever array with tunable on-site nonlinearity is proposed for experimental study on dynamics of intrinsic localized mode (ILM). In this paper, the cantilever array is first introduced and the equation of motion is derived. An experimentally excited ILM is shown and compared with the corresponding ILM obtained numerically. In addition, an unstable ILM is also shown with its waveform and Floquet multipliers.
