MIMO Vibration Controller
Spider-80M
The Spider-80M platform is based on the efficient Spider-80Xi architecture and is dedicated to MIMO VCS control and MIMO structural testing applications. Each Spider-80M chassis features 8 outputs capable of carrying out 6-degree of freedom MIMO testing. One Spider-80M chassis and multiple Spider-80Xi chassis can chain together to form a very large system with up to 504 input channels.

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.

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.

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.

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.

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:

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.

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.

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.

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.
