A macro-mechanical cantilever array is newly proposed for experimental investigations of intrinsic localized mode (ILM). There has never reported such a macro-system which show ILMs mechanically. The array consists of cantilevers, electromagnets faced on the cantilevers, elastic rods for coupling between cantilevers, and a voice coil motor for external excitation. Nonlinearity appears in the magnetic...
Intrinsic localized mode (ILM) is spatially localized and temporally periodic oscillation in nonlinear coupled oscillators. We numerically investigate the dynamical stability of ILMs in a microcantilever array, in which ILMs were experimentally observed by Sato et al. It is found that the stability change of ILMs is due to the ratio in nonlinear potentials. This phenomenon also occurs in the array...
