Multiple-Input Multiple-Output (MIMO) FRF Testing
EDM Modal MIMO FRF Testing includes a dedicated test setup and operation process flow using multiple simultaneous shakers to acquire FRF signals. Using a large channel count data acquisition system (i.e., Spider- 80X or Spider-80Xi), this shaker excitation method provides much higher efficiency and accuracy for the FRF measurements while minimizing local stresses on the test article.

Multiple-Input Multiple-Output (MIMO) Sine Test
EDM Modal Sine Testing includes a dedicated test setup and operation process flow using a single or multiple modal shakers outputting a sine wave to acquire FRF signals. The Source Output type is either Swept sine or Stepped sine. The sweep mode can be linear or logarithmic. The FRF signals of each measurement DOFs with respect to defined reference DOF will be constructed. The output drive level can be defined to run the test under no control strategy, or the response of a control channel can be specified to run the test in a closed loop.

Multiple Shaker Control
EDM Multi-Shaker Control (MSC) is a software option included in the EDM testing package along with VCS. Multiple Shaker Control provides one centralized interface to interact with multiple controllers running separate tests at the same time. Multi-shaker controllers are not time synchronized unlike in MIMO VCS, in which all drives are time synchronized.

Operational Modal Testing
EDM Modal Operational Modal Testing (OMA Testing) includes a dedicated test setup and operation process flow using ambient vibration data. Using a large channel count data acquisition system (e.g., Spider- 80X or Spider-80Xi), the excitation method provides a much higher efficiency and accuracy for FRF measurements while minimizing local stresses on the test article.

Order Tracking Analysis
Order Tracking is a general term describing a collection of measurement functions used for analyzing the dynamic behavior of rotating or reciprocating machinery for which the rotational speed can change over time. Unlike the power spectrum and other frequency-domain analysis functions where the independent variable is frequency, Order Tracking functions present the data against multiples (Orders) of the variable shaft running speed.

Automated Production Testing
Automated production testing is critical in today’s competitive manufacturing environment. Companies can no longer rely on variable costs, non-uniformity, and potential health hazards that come with a laborer-based manufacturing line. This is no less true for sound and vibration tests, ranging from in-process burn-in tests to product validation and verification tests. The measurement tools and intelligence behind present day manufacturing include data acquisition equipment as well as closed-loop...show more -

Chamber Controller Software
EDC (Embedded Device Control) is specifically designed software for Sentek chamber system controllers running Temperature and Humidity environmental tests. The EDC software features an intuitive interface, a powerful data review function and live data viewing. The combined EDM controller software provides one central location to set up parameters and a schedule between all three environments, with or without a connected controller. The powerful import and export features allow users to easily transfer test configurations between computers.

Combined System Controller Software
Designed and manufactured by Crystal Instruments, the Spider-101i controller is a key element of the Sentek Dynamics THV Series AGREE (Department of Defense Advisor Group on Reliability of Electronic Equipment) chambers. These chambers provide combined temperature, humidity, and vibration testing in addition to environmental and reliability testing for a wide variety of aerospace, automotive, medical, commercial, and independent test lab applications. Temperature, humidity, and vibration are controlled with high accuracy and are synchronized to simulate the actual physical environment products experience in the field.

Correlation Analysis
EDM Modal Correlation Analysis allows the user to correlate two modal models; EMA and/or FEA models. Comparing the experimental data with that acquired through finite element analysis helps in validating the test results. Users can import the geometry model and mode shape data from FEA or EMA software. A modal mapping procedure is executed to match the EMA and FEA models. After this matching procedure, the new mode shape information from FEA is interpolated and the FEA modal parameters are displayed alongside with EMA results. Finally, to observe the correlation between the results from the two methods, a Cross-MAC matrix is calculated and shown.
