Vibro-kit for simulating rotating machinery

A compact tool for simulating rotating machinery measurements.

The new VIBRO-KIT is designed for simulating rotating machinery measurements. It has application to educational settings, such as schools and university laboratories, providing a playground for countless experiments.

Made of solid aluminium, as are most of our instruments, it consists of small electric motor, a bearing, two optical strip-tape angle sensors, two encoders and a spring on one side. The RPM can be controlled manually with a turn knob, and you can even define ramps, cycles, etc. with the built-in display. Furthermore, an external analogue voltage (or even PWM signal) can be used to control the RPM.

FUNCTIONALITY:

• Manual RPM control (turn knob, display)
• Definable ramps (runup, coastdown, hold time and multiple cycles)
• RPM control by external voltage (e.g. step curve)
• External PWM input
• Different angle sensors (2 optical strip tape, 2 Encoders)

As with all DEWESoft® interfaces, the software automatically is selected based upon which application is being used. Place an accelerometre in various positions and measure the vibration level, display the result in the FFT Analyser and check Global Level, RMS, and Peak-Peak. The powerful cursors allow you to easily determine the max amplitudes as well as the harmonics and sideband modulations. Vary the RPM and display the time history data in the 3D FFT waterfall graph.

To separate engine-based harmonics (orders) from structural resonances, use the Order tracking module and perform a runup or coastdown through the whole RPM range. Extract single orders and see their contribution to the overall vibration level.

Some frequencies might arise from faulty bearings. You may wonder, are they still healthy? Simply place the bearing markers in the spectrum.

If the first order is too high, use the Balancing module to improve the result. Screws can be mounted on the discs (there are 20 positions around the circle) to correct it. The step-by-step procedure guides you through the process.

If you are interested in angle-based measurements, use one of the angle-sensors as a base, and calculate the rotational vibrations. The spring will create heavy torsional vibrations, which can be analysed up to very high precision at high RPM with our Supercounters hardware.

With the mathematics and analogue out functionality for steering RPM, the combinations grow almost endlessly to simulate practical application in the lab.

APPLICATIONS:

• FFT waterfall
• Order tracking
• Bearing fault detection
