Back to: VibrationVIEW Syllabus

In Sound and Vibration (Feb 1999), Robert Frey writes about the importance of university students working with “automated, computer-based data acquisition systems” in connection with vibration studies. The basic components required for closed-loop vibration testing are:

Electrodynamic or servo-hydraulic shaker
Transducer/sensor (typically an accelerometer)
Vibration controller hardware
Software package (such as VibrationVIEW)

Vibration Controllers

The VR9700, VR10500, and ObserVR1000 are vibration controllers that are compatible with the VibrationVIEW software.

Vibration controllers:

Send signals to the shaker amplifier to run the shaker excitation as defined by an output signal
Receive data from transducers
Receive outside information via remote inputs/outputs (e.g., current and voltage monitors or low voltage relays)

Two examples of shaker test setups with a stack of vibration controllers and a workstation PC.

Demonstration Mode

For educational purposes, VibrationVIEW can operate in Demonstration Mode. This test mode generates data as if the test profile was being run on a shaker.

Please note that the test profiles in the appendix are designed for Demo Mode only. Before running a test on a shaker, you must set system limits to prevent damage to the shaker or other equipment.

VibrationVIEW for Vibration Control and Test Reporting

VibrationVIEW includes various software modules to meet industry requirements, including foundational Sine, Random, and Shock modes.

Applications of VibrationVIEW

Design a vibration test and simulate a test run
Enter standard test profiles
Set up and safely monitor vibration tests
Graph data and add cursors or annotations
Save a test and generate a profile from the data
Replicate field-recorded data on a shaker
Limit test profiles to protect the shaker and other equipment
Generate professional test reports
