Hi,

 

Anyone know how to convert acceleration data to displacement time dat ain hypergraph with the function of zero mean after conversion? As if i simply double integrate it, displacement data are not vibrate in zero mean level while in real case, it should vibrate in zero mean level.

    Just right click on the curve in the plot browser (the curve list on the left) > single curve math > double integral > this will immediately plot the curve on the same plot.

    Hi, can you elaborate more on this? I want to convert the attached acceleration vs time graph to displacement vs time graph and export it to excel.  I am unable to find the double integral option under math in Define curves.

    Right Click on the curve and select Single Curve>> Double Integral

    This saved my time. I used to integrate twice using the math option.
