Shaker Sizing (F=MA)

VR4600

The 606F-lb pk system is one of the largest of the current family of Vibration Research systems. The large diameter armature adapts to many test requirements with a minimal amount of fixturing. High lateral and axial stiffness decrease problems associated with off-center loads. Unsupported horizontal operation is possible on many loads. The cooling blower is direct coupled to the shaker to give the maximum performance. An optional slip table is available for horizontal testing. Optional load supports allow testing loads with a high center of gravity. The suspension stiffness is adjustable. Electronic load compensation allows heavier loads.

VR5200HF

The 13F-lb pk system is a rugged, full featured, small permanent magnet shaker. It is ideally suited for the production screening of small components, engineering design verification/evaluation, or for larger transducer calibration systems. The shaker features a 2.125-inch diameter table with multiple attachment points, and an extraordinary 0.5-inch stroke. It has a linearly compliant armature suspension that is also suitable for modal testing with a current source amplifier. The High Frequency version with its slightly heavier armature has an extended full force frequency range of up to 14KHz with operation to 20KHz at 7lbf pk sine, and a dual thread center mounting hole with #10-32 threads for mounting accelerometers and other vibration transducers. Available in two different impedance ranges, the VR5200-HF series are easily matched to most amplifiers yielding the maximum system performance.
