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.
