The analysis of the raw vibration data was done in Matlab, and was completed by a series of programs written by Tim Slaton and Rachel Fenn. The programs are outlined below. Converts the velocity matrix into a single column and subtracts an offset to make the average velocity zero. Uses Fourier transforms to convert velocity to the frequency domain and computes the power spectra, and integrated power. Plots the four channels of velocity data against time.
Function creates and plots a histogram of the velocity data.
Writes all plots to file. Writes the power spectra and integrated power spectra data, in tables, to a file. Writes the velocity data, in tables, to a file. Writes the histogram velocity data, in tables, to a file. Plots 24 hours of rms values.
