I don't have a specific set of questions in mind. Try searching stack overflow for "peak detection" or "find_peaks_cwt". I would think you would want the individual vectors but you could get a vector sum as sqrt(a_x^2+a_y^2+a_z^2). The FFT output should give you each of the different frequencies. It will just have several peaks, each one representing a different frequency.

Also, If my accelerometer has measurements in 3 axis, do I need to process each axis separately or is there a way to get an absolute signal? Additionally, the gearbox I will be measuring has multiple degrees of freedom, what tools can I use to classify all the different frequencies I will get? | |
