Tools for Testing
March 29, 2018
The basic components required for closed-loop vibration testing are:
- Test control and analysis software, such as VibrationVIEW
- Vibration controller, such as the VR9500, VR10500, or ObserVR1000
- Power amplifier
- Electro-dynamic or servo-hydraulic shaker
- Transducer (typically an accelerometer)
VibrationVIEW includes System Check to test and calibrate a system. Optional VibrationVIEW software modules include Sine, Random, Shock, Field Data Replication (FDR), and many more.
Each module has various sub-options focused on specific test requirements. For tutorials on how to run tests and create reports in VibrationVIEW, take the VibrationVIEW Syllabus course.
VibrationVIEW is capable of operating without a shaker in Demonstration Mode. This mode generates simulated data as if the test profiles were being run on a shaker.
Note: The sample test profiles provided in VibrationVIEW are designed for Demonstration Mode only. Before running a test on a shaker, make sure the System Limits are properly set or the shaker could be damaged.
Controllers send signals to the shaker via the power amplifier to generate shaker excitation in a controlled manner as defined by a specific output signal. They are responsible for the vibration observed on the shaker head. Controllers also receive data from transducers and information via remote inputs/outputs (e.g., current and voltage monitors, low voltage relays, etc.).
The VR9500, VR10500, and ObserVR1000 can all be used as a vibration controller. The ObserVR1000 also functions as a dynamic signal analyzer.
