From: Data-driven modeling of subharmonic forced response due to nonlinear resonance
(a) Experimental setup of a water tank horizontally excited by a motor14. The cameras attached to the rig record the surface profile. (b) Previous SSM modeling of sloshing forced response is only accurate up to moderate excitation amplitudes. At the highest amplitude (green top branch), the water response becomes multiharmonic, not captured by a 2D SSM model11. (c) The surface elevation at the left tank wall at the highest excitation amplitude has a period three times longer than that of the forcing. (d) Snapshots of the water tank at three subsequent forcing periods show a recurring pattern of collapse in every third cycle.
