Lateral Excitation Shaker Stand

Model 2050A for Modal Shakers

The Model 2050A Lateral Excitation Shaker Stand provides a versatile means of adapting a modal shaker for horizontal input. Automobiles, aircraft, space structures, and civil structures often require a means of inputting lateral force. The stand facilitates excitation with a tensioned "piano" wire stinger which significantly reduces force measurement errors from unmeasured transverse forces. Combining both lateral and vertical excitation more evenly distributes input energy for better signal to noise levels, and helps to excite uncoupled lateral structural modes. The 2050A allows the shaker to be precisely located in both the horizontal and vertical directions.

Benefits:

• Reduces force sensor measurement error with "piano" wire stinger.
• Ensures proper alignment with coarse and fine adjustment.
• Optimizes stinger length with horizontal adjustment.
• Decouples shaker motion from dynamics of stand.
