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:

Vibration Diagnostics System
VDS
-
The Vibration Diagnostic System (VDS) is a vibration data management system designed specifically for the machinery Predictive Maintenance (PdM) community. It harnesses the graphic display capabilities of Crystal Instruments EDM Software for the work of machinery vibration analysts.

MESA Vibration Control
-
MESA tests are specifically required when the unit under test is too heavy or too big and exceeds the capabilities of a single shaker. In a MESA application, multiple shakers provide excitation to the test specimen in a single axis. Different relations like same magnitude and phase for drives, different phase for drives, different magnitude and phase for drives, can be set for this MESA test.

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.

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.

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.

EDM Post Analyzer Software
-
The Post Analyzer application is used for the post processing of previously recorded time stream data. Post processing includes data conditioning, Fourier transform operations, and specialized analyses such as order tracking and octave analysis.

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.

Product
Acoustic Control
-
Acoustic Control provides accurate control for high-level noise testing of reverberant chambers or progressive wave tubes. Based on the Spider hardware platform, Acoustic Control achieves quick and reliable control of the noise level to the reference octave spectrum and the overall sound pressure level (OASPL). Included safety features guarantee the safety of the unit under test.

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.

Product
Standard Modal Analysis
-
EDM Modal Standard Modal Analysis provides the user with a complete arsenal of tools, from FRF data selection and parameter identification to results validation and mode shape animation.

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.
