Frequency Response Function
FRF
-
FFT Spectral Analysis. Frequency Response Function (FRF) is a commonly used measurement type of the Dynamic Signal Analyzer. FRF is defined as the ratio of response i.e. acceleration, velocity, or displacement with respect to the excitation force which is the reference.

Real Time Digital Filters
-
Real Time Digital Filters can be used to filter a measured signal in real time. Filter characteristics can be defined by the user to meet the requirements of a specific application. Real-time digital filters are applied in the data conditioning phase. The filters are designed with a graphic design tool and then uploaded to the front-end for real-time calculation. The graphic design tool defines the filter performance vertical axis with a dB scale. The horizontal axis is defined as relative frequency.

MIMO Vibration Control Overview
-
MIMO Testing has gained a huge momentum in the past decade with the development of multiple shaker table systems, the availability of Multiple-Input Multiple-Output (MIMO) controllers, and the readiness of the standards (e.g., Mil STD 810G method 527 and IEST DTE 022 working group recommendation). The Multiple-Input Multiple-Output (MIMO) Control System includes the following:

Route Based Vibration Data Collector
-
The Crystal Instruments CoCo series are portable devices for vibration monitoring and predictive maintenance applications. The system consists of a CoCo analyzer and the Engineering Data Management (EDM) software. The CoCo is used to make field measurements and the EDM software in Vibration Data Collector (VDC) Mode is used to setup the CoCo hardware and define routes before field measurements, and to download data from the CoCo to analyze and archive afterwards.

Structural Testing Application Examples Using EDM Modal
-
Illustrated below are some customer applications in varying industries who are using the hardware and software by Crystal Instruments to analyze and understand the structural properties of their test specimen(s). Analyzing the modal characteristics namely natural frequencies, damping and mode shapes of the test unit further helps in improving the design to enhance the mechanical behavior of the test unit.

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.

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.

Shock Response Spectrum Analysis
-
A Shock Response Spectrum (SRS) is a graphical presentation of a transient acceleration pulse’s potential to damage a structure. It plots the peak acceleration responses of a bank of single degree-of-freedom (SDOF) spring, mass damper systems all experiencing the same base-excitation as if on a rigid massless base. Each SDOF system has a different natural frequency; they all have the same viscous damping factor.
