VibrAn - vibration analyzer and logger
By Denis V. Komissarov
VibrAn is designed for estimation of machines vibration ranges.
The program works with accelerometer sensor embedded in your cellphone. It will get the uncooked knowledge from the sensor, process it and exhibits visually the end result.
Vibrations from machine (under estimation) needs to be transferred to the phone's physique. It could be done by inserting the phone over the machine. If machine vibrates too intensive then it's better to dump such vibrations prior transferring it to the phone's body. For dumping extreme vibrations one might use spacer between the machine and telephone made from thick cloth or insulation foam.
Main features:
* Plot vibrations amplitude along the time line (time domain representation);
* Plot vibrations spectrum (frequency domain representation). On most telephones there shall be 0-50Hz spectrum vary in normal mode and 0-100Hz range in Turbo mode;
* Save raw accelerometer data in to the file (for further off-line processing);
* Loading of previously saved knowledge for evaluation and comparability;
* Processing of loaded knowledge with: Fourier rework, reverse Fourier rework, band move filter;
