Abstract：Abstract: With an inverted pendulum fixed on vibration base as the target of research, the nonlinear characteristics of the device with vertical simple harmonic motivation is studied by experiment. The technique feasibility of the system used in ocean wave power generation was discussed, which provided experimental evidence for ocean wave power generation. The angular displacement collection system of a pendulum was designed. The damping and natural frequency was measured, which provided a basis for numerical simulation and guided vibration experiment of the inverted pendulum with parametric motivation. The vibration spectrum and phase diagram of the inverted pendulum system were obtained by measuring time domain data, which show that large periodic rotation, periodic rotation with resonance and stability vibration exist in the motion of the inverted pendulum with parametric motivation and then the model has the characteristics of good absorption for ocean wave power energy and low consumption. Therefore, the inverted pendulum model of ocean wave power generation has important application prospects
