By analyzing the elastic rod of radial pendulum and the natural vibration frequency of the azimuthal-radial pendulum,the pendulum Lissajous figure is studied by using the method of camera exposure. We analyze the effects of some parameters including the length of the cycloid,the initial release angle and the quality of the pendulum on the trajectory of the pendulum. It is found that the experimental results consistent well with the theoretical predictions.
