Vibration analysis 4.3.11

The application analyzes the data from the phone's accelerometer and builds a vibration spectrum. This enables the evaluation of not only the strength and frequency of vibration but also the speed of rotation of various mechanisms, such as fans, motors, and other rotating components, as vibration frequency often coincides with the frequency of rotation. It can be beneficial in assessing the quality of fans and motors, verifying if their actual parameters align with the manufacturer's specifications, and can aid in monitoring malfunctions like issues in bearings. Moreover, it can assist in evaluating the quality of assembly and balancing homemade mechanisms with rotating parts.

To prevent potential damage due to excessive vibration, avoid subjecting your iPhone to intense vibrations. If vibrations are too strong, consider using a foam material pad or placing your iPhone at a safe distance where the impact of vibrations doesn't pose a risk to your device. Using a foam pad not only reduces vibration transmission but also enhances contact between the iPhone and the vibrating part, leading to more precise results.

Key features of the full version of the application include:

• Choice of units of measurement for X-axis (Hz or RPM) and Y-axis (g, m/s², ft/s², mm/s, in/s (ips), mm, mil, dB(A), dB(V)).
• Variable FFT sizes for different types of accelerometers, offering flexibility on data collection time.
• Various frequency scale options.
• Peak frequency detection.
• Customizable settings for data collection.
• Octave bands and window functions for enhanced analysis.
• Tools for calibration and adjusting accelerometer settings.
• Data storage and export features. Compatibility with desktop/laptop computers and other iPhones via iTunes.
• Capability to connect Bluetooth accelerometers.

When converting acceleration to speed or displacement, it is essential to note that noise may dominate at lower frequencies while excessively high frequencies can result in inaccurate calculations. Unrealistically high speed or displacement values might indicate false frequencies beyond 50 Hz.
