Experior Laboratories recently expanded its dynamic testing capability with another new vibration system.

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.

Similar to Experior Labs’ other model T4000 shakers, the new system offers 3” stroke with a 40,000 force-pound sine and random vibration capability. The 480kVA UD T4000 amplifiers provide a boost to its shock capability as well as reduced wear and improved uptime for demanding vibration campaigns.

Paired with the UD T4000 shaker is a custom 72”x72” high-performance precision slip table designed and manufactured by TEAM Corporation. Compared to a traditional slip plate resting on an oil film over a granite surface, the TEAM table has a slip plate supported by a continuous five by five grid of TEAM film hydrostatic bearings. The design of the T-Film bearing allows direct transmission of virtually all test object loads directly into the base and is accomplished by the hydrostatic bearing design.

The T-Film bearings have several benefits over 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. Additionally, hydrostatic bearings have significantly increased load capability, meaning the table can accommodate much heavier test articles.
