Automation & Controls
Automation is the use of control systems (such as numerical control, programmable logic control, and other industrial control systems) to control industrial machinery and processes, reducing the need for human intervention.

Automation & Controls
Time Waveform Replication Vibration Control
Time waveform replication (TWR), also known as long time history (LTH), exactly replicates, in the laboratory, vibration environments using data obtained in the field. Field measurements, such as a vehicle’s road test or an aircraft flight run, can be imported into the host PC, compensated for suitability to the shaker
Resonance Search, Track And Dwell Vibration Control
Resonance search, track and dwell (RSTD) is an invaluable test for automated fatigue testing. A sine sweep is used to detect the resonant frequencies of the device under test (DUT). The test then dwells upon these frequencies for a specified period or number of cycles, automatically tracking changes in resonance
Transient Time History Vibration Control
Transient time history (TTH) allows the user to simulate real-world shock transients based upon actual field measurements. Transients are short-lived vibration events characterized by waveforms that start with relatively high amplitudes that quickly dampen out. Compensation can be applied to ensure the generated waveform is compatible with the target shaker
Classical Shock Vibration Control
Classical shock control creates a series of pulses to excite the device or structure under test, measures the structure’s response and performs a spectral analysis to determine its response and resonance characteristics. This type of testing profile offers higher accuracy and repeatability than regular drop-test methods. USE SCENARIOS Shock testing
Random Vibration Control
The random vibration (or excitation) test profile simultaneously excites all resonant frequencies of any given payload, thus it is well suited for product qualification tests and for characterizing a structure’s dynamics. A fast loop time is important for high accuracy, and so are multi-channel control, notching, and real-time analysis. USE
Sine Vibration Control
Sine control creates excitation with analog-quality drive signal and user-programmable sweep parameters. This test profile is particularly useful for studying the structural dynamics of the device under test, as it enables accurate measurement of dynamic response at resonances. Since sine control concentrates all the vibration energy at a single frequency,
