High-T_c superconducting levitation systems, achieving stable levitation without contact support, are expected to be applied to energy storage flywheel systems. These systems can be modelled as magnetic coupling of many magnets and superconductors. Nonlinearity of magnetic forces can cause complicated interactions between the magnets. Numerical analyses and experiments were carried out, investigating forced vibration of a 3 degree-of-freedom coupled superconducting levitation system. Motion pattern of each magnet in time and spatial correlation of all magnets' motion were analyzed by applying FFT, Poincare mapping and POD (Proper Orthogonal Decomposition) to time series data obtained by experiments and numerical analyses. It was found that change in pattem of vibration of each magnet can be accompanied by change in spatial correlation of all magnets' vibration.
