N2 - An n degree-of-freedom (DOF) periodic cyclic system with linear coupling stiffnesses and cubic nonlinear grounding stiffnesses is considered. This system possesses nonlinear normal modes (motions during which all masses vary equiperiodically) which are examined using an averaging method. One type of nonlinear mode detected is localized, corresponding to motions during which the amplitudes of a few masses are large compared to that of other masses, and thus the energy of vibration is spatially confined. Numerical simulations indicate that cyclic nonlinear systems can be designed so that motion confinement of externally applied loads occurs.
