Model 4522 Electrodynamic Shaker
The Glotech/Ling Model 4522VH Shaker is a low profile, wideband, electrodynamic shaker designed for continuous testing of large and heavy specimens at high levels of acceleration for product qualification, reliability acceptance, and production stress screening application. For higher force requirements call a Glotech/Ling Sales Engineer to discuss our 5522 upgrade package which increases the peak sine force rating for this shaker to 55,000 lbf.
The shaker employs Ling’s field-proven metallic loop flexures and dual high stiffness hydrostatic bearings for armature guidance. A unique new armature design which incorporates more efficient cooling techniques is the heart of the 4522..
The 4522VH body suspension employs the exclusive Lin-E-Air pneumatic isolation system that suspends the body on air springs located at the trunnions. This system incorporates bearings, which restrain and guide the body in motion in the thrust axis, simplifying alignment with auxiliary horizontal tables. The low natural frequency of this body suspension system virtually eliminates the need for expensive large reaction masses for most applications.
The closed-loop water-to-water cooling system in conjunction with the new moving element design allows the 4522 to operate at full force conditions for an hour without a significant rise in body temperature.
