| Abstract: | An experiment study on single pendulum system with vertical parametric excitation is presented. The single pendulum system is studied by numerical simulation, and an experiment is carried out on single pendulum based on the result of numerical simulation. Through an analysis of the phase diagram and frequency spectrum of experiment＇ s signal, the experiment finds the period doubling bifurcation phenomena with coexisting period-two and period-four phenomena. |
