Data Physics - Electromagnetic Vibration Tables

DP Logo 200px offers a wide range of Air- & Water-Cooled Shakers as also under water Shakers or Inertial and Modal Shakers. In the product line of Controllers we find a wide variety of systems and software to controll and analyse test runs.

The M series of modal shakers use linear bearings, in place of the more common suspension systems, to produce virtually zero axial stiffness and virtually zero mechanical damping. When combined with Data Physics’ linear amplifiers, operating in current mode, the resultant system force output will exhibit typically less than 1%.

When large structures need to be tested, inertial shakers provide the ideal solution. The central spigot is attached to the structure under test and the body then provides the inertial mass. These shakers have found applications for testing buildings, floor loading resonances, ship’s decks for helicopter loading, squeaks and rattle testing in cars, geological exploration, helicopter rotor simulation and active vibration cancellation.

SignalForce range of water cooled shakers are used for many different applications such as testing of automotive sub-assemblies, military and defense components, large electronic components, and even fully assembled satellites. By utilizing the dual hydrostatic bearings that are incorporated in the shaker design, payloads with high overturning moments can be tested without the need for external guidance systems. When direct coupled, the SignalForce water cooled shakers offer superior low harmonic distortion at very low frequencies and maximum displacement. This linear response is the result of inherent engineering discipline, where copper material is added to the center pole and the body, and cancelling the apparent inductance which otherwise makes for non-linear response at low frequencies. The water cooled shakers may also be supplied with horizontal slip table systems for 3 axis testing.
