Bringing Broadband 6-DOF Field Vibration Environments into the Lab

Commercially available vibration test systems able to reproduce and accurately control multiple-input, multiple-output vibration tests are often constrained by a limited frequency band due excessive tare mass and low natural frequencies of the fixtures. Consequently, their use in Department of Defense test facilities is limited to a select number of test profiles found in MIL STD documents and/or platform specific tests where the frequency band of interest is below 500 Hz. This frequency limitation has now been addressed with the introduction of a new 2000 Hz system based upon twelve electro-dynamic shakers hydrostatically coupled to the specimen mounting table. This system, called the Tensor 18kN, has been designed, built, and tested by Team Corporation and has been delivered to two sites in the USA. To read the entire published article, click here
