Vibration Testing
Experior Laboratories’ MIL-STD-790, NASA and JPL approved and ISO-17025:2017 accredited laboratory houses multiple state-of-the-art electrodynamic vibration testing systems that can handle the most demanding vibration and shock testing specifications.
For oversized and heavy payload vibration testing applications, Experior Labs’ vibration testing systems can be used in tandem to provide a combined 80,000 lbf for large articles. Such applications have included rocket engines, rocket stage separation actuators, satellites, orbital reflectors, electric vehicle batteries, railroad components and many more. Custom-made vibration testing fixtures and slip plates allow us to test parts of almost any shape and size.

72” Custom Guided Head Expander Capability
Experior Laboratories’ vertical vibration system features a custom-designed 72” x 72” guided head expander that offers the best dynamic response for vibration testing of large and heavy test articles.
High Performance Vibration Testing for Large and Heavy Test Articles
The newly installed system combines two test industry expert components, a new Unholtz Dickie T4000 vibration system and a TEAM T-Film Bearing slip table.
The TEAM T-Film bearings have several benefits overs standard oil film and linear bearings. The unique inverted T shape of TEAM bearings provides improved stiffness, load transfer and improved moment transfer to the reaction base. This minimizes slip plate deflection and cross axis vibration, as well as allows for test articles with a much higher overturning moment. The hydrostatic bearings have significantly increased load capability, meaning the table can accommodate much heavier test articles.
Vibration Testing at Temperature
Standard Temperature chambers range from -75°C to +200°C. All chambers feature portholes for routing supply lines and/or signal cables to and from the equipment under test and all are equipped with electronic data acquisition monitoring to allow real-time charting of climatic conditions through data files and spreadsheets. Custom and non-standard temperatures available. Contact us for more information.

Transportation Vibration Testing
Experior Labs’ dynamics laboratory can conduct Transportation Vibration testing per MIL-STD-810 Method 514 Procedure II “Loose Cargo Transportation”. During this vibration test, products are subjected to vibration profiles developed to simulate truck and rail shipments. The test severity, in particular, is for loose cargo transport in military vehicles traversing rough terrain.
Acceleration Testing
The main advantage of the Sine Burst is that it is performed on a vibration system, the same vibration system that performs other tests such as random and/or sine sweep vibration and shock testing. Further, test article sizes can be much larger and heavier than in a Centrifuge. Performing all dynamic tests on the same vibration system reduces test costs and time.
