Vibration Visualization
DSA
-
It is difficult to imagine the actual vibration level and distribution from the numerical display or the signals which are basically a mathematical representation of the vibration experienced by the structure under test.

Remote Condition Monitoring Software
-
The specially designed EDM-RCM software simultaneously connects multiple such Spider systems in addition to providing updated results of essential data for all Spider front-ends located throughout the world. The software provides a live view of data from any Spider system as needed and downloads recordings from any or all Spider front-ends for further analysis and inferences.

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) 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.

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.

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.

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.

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.

Whole Body Vibration Analysis
-
Whole Body Vibration (WBV) testing is a type of vibration analysis geared towards estimating the effects on the operator. There are three categories of concern for the operator, health and comfort, perception, and motion sickness. The goal for any WBV test is to ensure that under normal operating conditions there is no significant or lasting effect of the vibration experienced by the operator.
