Cumulative G force of XYZ sub channels

Pete

Hi guys,

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?

Pete

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"

Good question!

VibrationData Toolbox

We just compiled and are releasing Tom's VibrationData toolbox that has some shock combination analysis capabilities.

• Link to download the software (sneak peak of the new website)
• Article on Installation of VibrationData Toolbox
• Article on Importing Data into VibrationData Toolbox
• Article on Analyzing Data in the VibrationData Toolbox

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!
