Acquire, Analyze, Import Vibration Data
-
Reproducing actual field vibration data is a key feature of the APEX Series Vibration Controllers! It provides four distinct and important choices for analyzing and importing data for creation of random, transient shock, and time replication acceleration control (TRAC) tests. Collecting data and importing the information into the controller is accomplished by using the Signal Analyze/Transient Capture and Data Acquisition modes, or by importing stored ASCII file data. The Import Data Manger provides guidance and extensive editing options for optimizing the new test. The resulting test reference (time or frequency spectrum) can then be performed at the vibration test system.

Apex Series Hardware
-
APEX SL and APEX PRO advanced architecture incorporates multiple digital signal processors from ADI. The versatile and proven SHARC and Blackfin processors are the industry standard for high performance and power efficiency. This powerful control system hardware set is used exclusively for control loop processing and host communication, assuring accurate real-time control and simultaneous data acquisition, while all graphics related processing is reserved for the host computer’s multi-core processor.

Electrodynamic Shakers (Highest Force Air Cooled System)
K-Series
-
K-Series high performance electrodynamic shaker systems offer 100% air cooling, 3 inch (76 mm) stroke, and feature an output force up to 18,000 pounds (80.1 kN). They are available with a 16 inch (445 mm) or 24 inch (654 mm) armature outer bolt circle, allowing a variety of package sizes and fixture configurations.

Product
Slip Tables
-
Unholtz-Dickie offers three configurations for fully integrated slip table assemblies for vibration testing; the ST Series, HST Series and the CSTA Series. Horizontal slip tables are used for three-axis sequential testing (x, y, z axes) or used when it is necessary to maintain product positioning with respect to gravity.

Electrodynamic Shakers
R-Series
-
The R-Series vibration test systems are designed to provide reliable performance for medium and high force applications. The R-Series Shaker Armature incorporates a multi-ribbed design, which provides maximum stiffness and minimum weight, resulting in a high acceleration to specimen weight ratio and impressive acceleration and frequency performance.

Long Stroke Thrusters
Seismic Test Systems
-
Unholtz-Dickie offers the world’s first all air-cooled, electrodynamic long-stroke testers for telecommunications, earthquake simulation, and transportation applications. Up to 2,300 lbs (1,040 kg) of payload can be supported on a 48x48 inch (1.2 x 1.2 m) footprint on either the slip plate of the horizontal LS12H thruster or the bearing-guided head expander of the vertical LS12V unit. Both are driven by the highly reliable SAI120 SiC amplifier with an integrated switching cabinet for either vertical or horizontal testing. And because it’s an electrodynamic shaker, relatively high frequencies of up to 1,000 Hz can be achieved.

Command Link
-
The APEX Series Controllers offer an optional RS232 Amplifier/Shaker interface and a software command/status panel to operate UD’s newly enhanced SA and SAI Series amplifier/shaker systems. The SA-Command Link provides identical functionality as the standard SA Amplifier front panel switch buttons, LED status indicators and current/voltage meters. In addition, it provides a Power Save selection to automatically power down the UD SAI Amplifier/Shaker system after a test has finished or aborted, and current / voltage limits can be set to abort the test for added system / specimen protection. Now the complete UD test system can be initiated, monitored, and controlled from one convenient location.
