Shakers

Electrodynamic shaker systems below consist of a shaker and a matching linear direct-coupled power amplifier. Additional components may be added to the basic system to tailor it to your specific needs. These systems have been designed and manufactured with both its shakers and matching amplifiers in-tandem.

Shaker Sizing (F=MA)

Model VR4600

In the current family of Vibration Research shakers, the VR4600 is one of the largest. 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.

Model VR4044

The VR4044 is a permanent magnet shaker that features a direct coupled cooling blower to maximize the force available in a small package. The larger armature supports general vibration testing of components and subassemblies. High lateral and axial stiffness reduce problems associated with off-center loads. Unsupported horizontal operation is possible on many loads. A rare-earth magnet reduces the overall shaker weight for portable applications. The robust design of this shaker ensures a long service life, important when running extended duration testing.

Model VR5200HF

The VR5200HF is a high performance system which incorporates a compact high frequency shaker. This system offers the maximum performance from the shaker without a cooling blower. Full system ratings are available up to 14,000 Hz with reduced operation up to 20,000 Hz. This system is used for both general purpose high frequency testing and transducer calibration requirements. A voltage-proportional-to-output-current output signal is provided for modal test and other applications requiring force monitoring. The larger mounting surface of the ET-126HF easily supports the calibration of most vibration transducers and smaller high frequency assemblies and components for general purpose testing not requiring high acceleration testing. The shaker can support relatively heavy loads and is perfectly matched to the amplifier, which makes this the most versatile system of its size.
