Vibration Lite 1.0


Category: Utilities
Price: Free (iTunes)

Description:

Vibration Lite is the Lite version of Vibration, the full featured vibration spectrum analyzer for the iPhone.

Vibration Lite is a true vibration spectrum analyzer using the built in accelerometers inside the iPod Touch and the iPhone. It acquires and displays time series data, optionally removes DC bias, applies a Hamming window and performs an FFT on each channel to produce frequency spectra. The 3-channel accelerometer has a sensitivity of approximately 0.02g and a range of ±2g making the iPhone and iPod Touch sensitive enough to analyze the vibration of most moving machinery.

In many applications Vibration Lite can be an excellent portable alternative to a commercial spectrum analyzer. In predictive maintenance applications Vibration can help identify bearing defects, shaft misalignment, imbalance, and structural resonant frequencies. Vibration Lite is also useful for monitoring the acceleration of part and material handling equipment.

Vibration Lite is also an excellent tool for iPod and iPhone game programmers. The application provides an ideal way to record the output of the accelerometers for particular user actions. This data can then be plotted offline allowing the programmer to best determine how to process the data.
