CHARACTERISTICS

Compact-yet-powerful, this shaker combines a wide frequency band, maximum accelerations and relatively high forces to offer a versatile and cost-effective solution for a variety of testing needs that include product qualification, machinery diagnostics and instrument calibration.

Suitable for vibration and shock tests using sinusoidal and random excitations, V721 can impart peak sine forces of 2.9 kN (652 lbf) and operate in frequencies ranging from DC to 4000 Hz. Thanks to a built-in pneumatic load support system, the shaker is able to accommodate payloads up to 100 kg (220 lb) with full relative displacement.

For enhanced acceleration and velocity performances, the shaker’s armature incorporates a magnesium frame that is both lightweight and rugged; it also features a unique suspension mechanism that provides axial stiffness and improves lateral and rotational restraints.

Standard mounting for this shaker consists of a solid cast-iron trunnion which allows the thrust axis to be locked in the vertical or horizontal position. In turn, the trunnion supports are fitted with four air-isolation mounts to prevent shaker-generated vibrations from travelling through the floor.

Additionally, a number of optional and customizable features are available to tailor the V721 shaker systems to your specific needs.
