This is a long shot but the device I am testing give off varying acceleration in X, Y, Z direction. Is there a way to get the average acceleration of all three sub channels?
Never mind. I found my answer.
Acceleration=SQRT((X peak-X valley)^2+(Y peak-Y valley)^2+(Z peak-Z valley)^2)
The purpose of subtracting valley value from peak value is to get "Peak-to-peak amplitude"
We just compiled and are releasing Tom's VibrationData toolbox that has some shock combination analysis capabilities.
Within the VibrationData Toolbox under shock response spectrums there is a triaxial analysis component.
I analyzed the punch data shared here.
It then generates a ton of plots, one of which includes a worst case uniaxial acceleration.
This question comes up often though, I'll add this to the feature request list to calculate a cumulative/worst-case uniaxial acceleration in the analyzer software. Thanks for the suggestion!
