From: Self-propulsion of a grain-filled dimer in a vertically vibrated channel
(a) Simulation result from the simplified model in the motion toward the large-grain-filled ball (TLG mode). f = 25 Hz, Γ = 2.5. (b) The blue, red and yellow lines represent the vertical position of SG filled ball, LG filled ball and the vibrating plate as a function of time. The vertical bouncing mode from the simulation is very similar with the experimental observation. (c) Instantaneous horizontal velocity of LG ball vs time. (d) Horizontal velocity of LG ball vs the corresponding vertical distance difference between the SG and LG ball.
