Figure 6.
The experimental arrangement shows a shaker exciting a unit cell while three P S V-500-3 D laser vibrometers measure its dynamic response. An Overview view and a Top View of the unit cell are provided, showing the internal mass and supporting structure. Dashed lines connect the unit cell to the three measurement devices, indicating simultaneous vibration monitoring. The layout illustrates the equipment and measurement configuration used for three-dimensional vibration analysis of the unit cell.Visualisation of the fundamental translational vibration mode of a fixed-base unit cell using a PSV-500-3D vibrometer (the undeformed unit cell shape is overlaid in black for comparison)
