By obtaining the motion trajectories and energy transfer characteristics of the particles, the dynamic behavior of the particle system is further studied. Currently, most of the existing related experiments stay at two-dimensional or quasi-two-dimensional drive, and the research on the motion behavior of particle systems under three-dimensional vibration drive in space is a frontier topic.
