Vibration Testing
Experior Laboratories’ MIL-STD-790 approved and ISO-17025:2005 accredited laboratory houses multiple state-of-the-art electrodynamic vibration testing systems that can handle the most demanding vibration and shock testing specifications.
For extreme vibration testing applications of large platforms, Experior Labs vibration testing systems can be used in tandem to provide a combined 80,000 lbf for large articles (example: 14 ft actuator for stage separation). Custom-made vibration testing fixtures and slip plates allow us to test parts of almost any shape and size.

Unholtz-Dickie Vibration Testing System Armature
The Unholtz-Dickie Induct-A-Ring armature uses a solid metal coil with no windings on the moving armature, allowing it to be driven at extreme G-levels without driver coil failure.
By comparison, conventional vibration testing system armatures have a wound coil that’s epoxy bonded to the armature. During High-G level vibration testing 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 Ultra High-G level vibration testing and shock testing. The Unholtz-Dickie Induct-A-Ring armature solves this problem.
