Statistical analysis on a typical TSG mode. χ = 2.75, m = 25.82 g, f = 25 Hz, Γ = 2.5. (a) Upper panel, instantaneous horizontal velocity of SG ball vs time. The lower panel, vertical position of both balls and the vibrating plate as a function of time. The cartoon drawing indicates the steric configuration of the dimer as it impacts the vibrating plate. (b) Horizontal velocity of SG ball vs the corresponding vertical distance difference between the SG and LG ball, showing irregularity. (c) Power density spectrum of the horizontal velocity vs time. (d) Power density spectrum of the vertical velocity vs time.
