| Summary: | Shaft misalignment is a condition in which two connected rotating machine shafts are
not on the same rotational axis. This condition can result in high vibration and premature
engine failure. The misalignment is corrected through shaft alignment based on
misalignment measurement results. Measurements can be made using a laser or dial
indicators measuring instrument. Laser measuring instruments are practical but require high
investment costs compared to dial indicators. Meanwhile, the dial indicator is relatively
cheaper but less practical because it requires a manual reading and interpretation of data.
This process has the potential to cause errors in reading and interpreting data. Therefore in
this study, a misalignment measurement system was created to bridge the problems in those
two measuring instruments.
This research will carry out the design, manufacture and performance evaluation of
of a misalignment measurement and interpretation systems based on Arduino and Matlab.
The system uses two digital dial indicators so a double radial method can be applied. This
system was also equipped with a sensor module MPU6050 to measure the angle of rotation
of the shaft. The digital dial indicator and the MPU6050 sensor module were connected to
the Arduino for early signal processing purposes. The results of this processing were sent to
a computer via the HC-05 bluetooth module for advanced signal processing. Advanced
processing was carried out using a user interface. This user interface was created with Matlab
App Designer. This user interface works automatically to provide a recommendation of
inboard and outboard foot shifts in order to minimize misalignment.
Based on the experimental tests carried out, the misalignment measurement system
has similar performance to measurement using an analog dial indicator with face and rim
method. Both measurements have different correction values in the amount of 1-3% for push
button mode and 2-5% for graph mode which relies on the MPU6050 sensor. |
