ResetVR4600
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.

VR5800
The 500F-lb pk system uses a larger shaker with a large 6-inch diameter armature table, making 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 system is equipped with a degauss coil to ensure a 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.

VR4044
The 44F-lb pk system 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.
