Using LTspice to Analyze Vibration Data in Condition-Based Monitoring Systems

Using LTspice to Analyze Vibration Data in Condition-Based Monitoring SystemsThis article describes how to use LTspice® to analyze the frequency content of vibration data in condition-based monitoring systems in order to give an early warning of motor failure in industrial machinery. The article explains how to take X, Y, and Z plane data from a Microsoft Excel® spreadsheet and convert it into a format to which LTspice can apply a Fourier transform to produce a plot of the harmonic content of the vibration data.
