VibMeasure

Floor Vibration Velocity Analysis is a tool that uses the iPhone's built-in sensors for vibration measurement and spectrum analysis. It's suitable for initial on-site observation, floor vibration trend checking, and daily measurement record organization. The app automatically analyzes Z-axis acceleration data after measurement, providing time-domain waveforms, dominant frequency, frequency band dominant frequency, fixed bandwidth velocity spectrum, 1/3 Octave velocity RMS, and overall velocity RMS, helping users quickly understand vibration characteristics. Measurement results can also be exported as a CSV file for easy subsequent organization and comparison. Main Functions: Displays real-time Z-axis acceleration values Customizes sampling rate and high-pass cutoff frequency Automatically performs spectrum analysis after recording Displays full-frequency peak and dominant frequency within a specified frequency band Displays overall velocity RMS Displays fixed bandwidth velocity spectrum Displays 1/3 Octave velocity RMS Exports measurement data as a CSV file Suitable Use Cases: Initial measurement of floor micro-vibration Observation of vibration during indoor equipment operation Comparison of repeated measurements at the same location Quick on-site inspection and record organization
