3 Technical data

3.1 Introduction

The new VIBRO-KIT is a compact tool for simulating rotating machinery measurements. It is meant for demonstrations or educational purposes such as in a lab or university. It provides a playground for almost unlimited experiments.

It's made of solid aluminum. It’s built of a small electric motor with a simple control panel, two bearings, two optical strip-tape angle sensors, two encoders and two different couplings on each side. One is rigid and the other is made of spring.

The RPM can be controlled manually by a turn knob, or you can completely define ramps, cycles, etc. with the built-in display.

Furthermore, an external analog voltage (or even PWM signal) can be used to control the RPM.

Functionalities:

● Manual RPM control (turn knob, display) ● Definable ramps (runup, coast down, 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)

Tacho 1 Out


Measuring an output signal from an optical sensor that is integrated below the rotating disk.

Tacho 2 Out


Measuring an output signal from an optical sensor that is integrated below the rotating disk.



3.3.5 Couplings The right encoder is connected to the spring coupling which damps high accelerations but may cause an oscillation until the moving parts are equalized. Black round plate has a white dotted strap on it which you can read with the tacho sensor.

Image 5: Flexible coupling on the right side

The left encoder is connected to the rigid coupling which eliminates any oscillations in regard to the accelerating.

Image 6: Rigid coupling on the left side



4 Possibilities of use

4.1 Super-counters

Additional equipment: SIRIUS with at least one CNT module (ACC+, …).

DewesoftX’s super-counters work on a 102.4 MHz internal time base, always, independent of the current sample rate. In comparison to standard counters, which only output whole numbers like 1,1,2,2,3,4, … one sample later, DewesoftX ® is able to extract the accurate values like 1.37, 1.87, 2.37, … fully time- and amplitude-synchronized. This is done by measuring the exact time of the rising edge of the signal with an additional counter.

Image 7: Super-counter

Frequency/super-counter mode has many advantages over traditional counter measurements.

The problem with traditional counters is that the value of the counter is latched only at a sample rate interval. Therefore, we only have discrete values on each sample. Since the counters can measure exactly where the position of the pulse is between two samples, we can calculate two things out of this: the exact interpolated position of the counter at the sample point, as well as the exact frequency of the pulses.

We connect the encoder to the CNT module. In DewesoftX ® software, we add the Counters.



Image 8: Counters

In the Counter menu, you will see all the available counter channels. Enter the setup of the channel where your encoder is connected.

Change the Basic application to the Sensor and choose the correct sensor from the dropdown list. If your sensor is not on the list, you can add it in the counter sensor editor.

Select the output channels that you want to show (angle, frequency, raw count).



Image 9: Counter menu

Enter the Measure mode and add a recorder visual control. Display the Angle and Raw count on the same recorder. When the Vibro Kit is running, press Freeze and zoom into the signal. You can see how DewesoftX ® interpolates the angle values and is not updated only when a new pulse comes from the angle sensor. The raw count value is increased every time a new pulse comes from the sensor.

4.2 FFT analyzer

Additional needed equipment: SIRIUS with one ACC, accelerometer.

Glue the accelerometer on the Vibro Kit. Connect the accelerometer to the SIRIUS ACC module, and enter the channel setup. Select the IEPE mode – if the sensor has a TEDS chip, the sensitivity will be recognized. Otherwise, enter the setup and change the sensitivity of the sensor manually.

Image 11: Channel setup

Add the FFT analyzer math module (with the click on the plus button More). Select the input channel (accelerometer) and set up the math.


https://training.dewesoft.com/online/course/digital-counters


Image 12: FFT analyser settings

Enter the measure mode and add the FFT channel on a 2D graph. Run the machine and observe the FFT.

Image 13: FFT math on 2D graph



On the FFT graph, you can show the markers and how FFT behaves with different parameters in the setup. For an explanation of all the parameter visit:

4.3 Order tracking

Additional needed equipment: SIRIUS with one ACC and one CNT module, accelerometer.

Glue the accelerometer on the Vibro Kit and connect it to the ACC module. Connect encoder to the CNT module. Open channel setup and set the acceleration sensor to IEPE mode and enter the correct sensitivity. Add an Order tracking module.

Image 14: Order tracking settings

Select the vibration and the frequency input channel. Detailed description of all the parameters can be found here: https://training.dewesoft.com/online/course/order-tracking

Enter the measure mode, and run the machine slowly from 0 RPM to 3000 RPM.


https://training.dewesoft.com/online/course/fft-spectral-analysis

https://training.dewesoft.com/online/course/order-tracking


The order tracking module creates a display with two 3D graphs to show order and FFT waterfalls, two 2D graphs to show the order harmonics and phase of the harmonics and a digital meter to monitor the RPMs of the machine.

Image 15: Order tracking screen

4.4 Balancing

Additional needed equipment: SIRIUS with one ACC (single plane balancing) or two ACC modules (dual plane balancing), accelerometer (single plane balancing) or two accelerometers (dual plane balancing), additional screws for balancing the rotor.

Select the input channel (vibration) and define the frequency source (counters, analog sensor, RPM channel). Balancing procedures should be done at constant RPMs.



Image 16: Balancing settings

Balancing is a step-by-step procedure. First, you need to perform the initial run, to get the initial unbalance vector. After that, you attach a trial weight, perform a trial run to get another unbalance vector. From those two unbalanced vectors, we calculate the correction mass that has to be added and the angle at which this should be added. You can perform as many steps as you wish.

https://training.dewesoft.com/online/course/balancing


4.5 Torsional vibration

Additional needed equipment: SIRIUS with 2 CNT modules and accelerometer.

Connect two angle sensors to SIRIUS. Add a torsional vibration module. Select the first (reference) and second angle sensor input and assign sensors to the counter channels.

Select the wanted output channel from the module. Detailed description of the parameters and setting can be found here: https://training.dewesoft.com/online/course/rotational-and-torsional-vibration

Image 18: Torsional vibration settings

Enter the measure mode. The plugin creates a new display with 2 XY recorders for displaying the rotational angles and torsional angle against the reference angle sensor.

On the time recorder, you can see the behavior of the rotational angle and observe how the vibrations change with the RPM.

● Set output voltage to some low value. Enable motor by holding RUN_SW for 1sec. ON is displayed.

● Disable motor by pressing RUN_SW shortly. OFF is displayed. ● Set desired motor voltage with encoder, range 0,00…6,00V steps 0,10V. ● Motor speed is shown in RPM, should use 18 PPR tacho wheel for correct reading. ● Check Voltage needed for desired RPM.
