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 VR5800
The VR5800 is one of the largest of the current family of VR’s vibration test systems. Its large 6″ diameter armature table makes it easy to adapt to almost any test requirement with a minimum of fixturing. The high lateral stiffness carbon composite armature suspension reduces problems associated with off-center loads and allows unsupported horizontal operation with many loads. The shaker is equipped with a degauss coil to ensure low stray magnetic field for sensitive applications. The modular, air cooled amplifier is direct coupled to the shaker to give the maximum performance at low and high frequencies. Digital meters display the system operating levels and complete shaker and external interlocks help protect the system from accidental abuse. Oil film slip table base systems are available for larger and heavier loads or loads with high centers of gravity.

Model VR5500
The VR5500 is our strongest permanent magnet field shaker system. Capable of up to 75 lbs force, the 3-inch diameter armature table is suitable for larger loads that require high vibration levels. The shaker’s full 1-inch armature stroke capability is ideal for many modal as well as low frequency general applications. The air cooled amplifier is direct coupled to the shaker to give the maximum performance at low and high frequencies and can be easily switched from voltage source mode for general testing to current source mode for modal testing applications. Dual meters display the system operating levels and complete shaker and user interlocks help protect the system from accidental abuse. A guided flexure table base system is available for larger or heavier loads and loads with a higher center of gravity.

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 VR4022
The VR4022 is a permanent magnet shaker that is used for both modal and general purpose testing. The compact size and light weight make a very portable package. This size is ideal for desktop applications. This lightweight armature shaker runs higher test levels without forced air cooling. It’s perfectly suited for testing of small transducers as well as electrical and mechanical assemblies. High lateral and axial stiffness reduce problems caused by off-center loads. Unsupported horizontal operation is possible on many loads. The frequency limit of 7000Hz satisfies high frequency test requirements.

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.
