CHARACTERISTICS

The most powerful shaker in our low-force range, V780 is also capable of achieving high accelerations while operating in a wide frequency band – a combination that makes it the versatile and economical choice for a number of testing scenarios, such as product qualification, quality assurance, machinery diagnostics and instrument calibration.

V780 is suitable for vibration and mechanical shock testing using sinusoidal, random, or transient excitations. It can deliver sine and random forces up to 5.12 kN (1150 lbf) and 4.23 kN (950 lbf), respectively; and features a usable frequency range from DC to 4000 Hz. The shaker is equipped with a built-in pneumatic support system that enables it to accommodate payloads up to 100 kg (220 lb) with full relative displacement.

For enhanced acceleration and velocity performances, the armature incorporates a lightweight, rugged magnesium table as well as a unique suspension mechanism that provides cross-axial stiffness and improves lateral and rotational restraints.

As standard, this shaker comes mounted on a solid trunnion and may be locked in the vertical or horizontal position for operation in either axis. The trunnion itself is supported by four air-isolation mounts to isolate the floor from shaker-generated vibrations.

Additionally, a number of optional and customizable features are available to tailor the V780 shakers to your specific needs.
