Vibration accelerometer (measure - store - analyze)

It's time to conduct vibration measurements with the easiest smartphone application for vibration analysis and measurements - made in Germany.

You can use this userfriendly and mighty app as an accelerometer to detect vibrations / oscillation, natural frequencies / eigenfrequencies and damping values of objects, machines and structures. Furthermore you can detect cable forces of cablelike elements like hanger of bridges. The tension force / prestressed force of a rope or wire will be calculated due to the first natural frequency of the cable.

Main features:

- Real time measurement of accelerations in all three axes (X,Y und Z)

- Real time frequency spectrum while measuring

- Storage/Reloading of all your measurement files on your device as .txt files

(transmission by e-mail)

- FFT-analysis of signal - generation of frequency spectra

- Userfriendly interaction with frequency spectrum

- Determination of damping values out of decay processes

- Detection of natural frequencies of structures

- Detection of cable force due to vibration measurement

- Detection of maximum accelerations and RMS-values

How to use the app:

Simply place your smartphone with the myFrequency app as an adequate alternative to a professional vibration meter ( vibrometer ) on any vibrating object and determine the relevant natural frequencies/ eigenfrequencies in just a few seconds. You can use this app also as seismometer to detect earthquakes.

The acceleration sensor records the vibration in all three axes and stores the signals in a text file on the device for direct analysis on the smartphone or for subsequent processing on the computer. The data can either be transferred via USB cable or directly in the app with an e-mail to the computer.

In addition to the frequency with the maximum acceleration amplitude, all other excited frequencies can be individually selected by swiping your finger over a detailed view of the spectrum.

This is a test version, to enable all features of the app please download the full version.

We hope to offer you an application that you can use for all kind of vibration measurements, in structural health monitoring also.

If you have any questions, comments or suggestions, please contact us so that we can continue to develop the app.
