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.

An excitation stinger consists of a thin, flexible rod, with attachment means at both ends. The stinger transmits force in the stiff axial direction and flexes laterally to reduce input side loads to the structure. This uniaxial force delivered by the flexible stinger increases the accuracy of the measurement. The stinger also helps to isolate the exciter armature from the structure, lessening inadvertent shocks and possibly preventing damage to a fragile exciter armature. Likewise, the stinger can protect a fragile structure from large, inadvertent excitations

Since the natural frequency does not vary appreciably with load, several mounts may be used to support a structure at various loading points with good agreement on overall system mounting frequencies. AirRides offer the highest degree of isolation of any type of vibration isolator.

• Excels in supporting "body-in-white" vehicles for modal testing.
• Provides extremely low mounting frequencies for large test structures.
• Eliminates "chatter" seen in coil springs.
• Eliminates multiple mounting frequencies, since AirRide natural frequency does not
  change significantly with changes in load.
• Compact in size, light in weight.
