Induct A Ring Shaker

The UD Induct-A-Ring armature utilizes a solid metal cylinder (ring) as the moving coil, with approximately 0.5 inch (12.7 mm) wall thickness. The force-generating AC currents in the IAR single turn coil are produced by induction, thus eliminating the need for current-carrying linkages between the armature and the shaker body .

By comparison, conventional shaker armatures have a wound coil that's epoxy bonded to the armature. During high G-level operation, this attached driver coil is subject to mechanical failure. It is an accepted fact that conventional driver coil armatures are not well suited for high-G SRS testing. The UD Induct-A-Ring armature solves this problem.

Vibration testers (also known as vibration analyzers, shaker tables, or vibration testing machines) are used to assess how materials and components handle vibrational forces, offering insights into durability and reliability.

The shaker sends the signal to the DUT that is attached to the shaker through a shaker-adapter and fixture. A feedback response is sent back to the vibration controller that compensates the signal to adjust it to the test specification. ... What is an Induct-A-Ring shaker?
