Division of curves

Hi,

 

I have created a curve of acceleration Vs frequency as well applied load Vs frequency.

 

But actually my aim is to draw a curve of accelerance (acceleration/ force) Vs frequency.

 

I think it can be done using division operation (math curve)

 

But don't know how to apply?

 

Does anyone knows much about this, please help me.... image/emoticons/default_sad.png' alt=':(' srcset='<fileStore.core_Emoticons>/emoticons/sad@2x.png 2x' width='20' height='20'>

    To divide two curves, 

     

    File > load > vehicle safety tools > then go to math in the menu > two curves math > divide > select the numerator and denominator,

     

    Use divide by zero if necessary for your case, i.e. if c1 is divided by c2, and if c2 has any zero values, then c1/c2 equals 0.

    I am not sure whether my process is right or not.

     

    The curves I plotted using build plots.

     

    I separated the window in to 4, 3 of the window I used for HG.

     

    So in 2nd window I have acceleration plot, 3rd I have load.

     

    And now from the 4th window if I am going for vehicle safety---math---divide its not coming the selection window for numerator nd denominator.

     

    But without any plot I tried, in that case the numerator denominator selection window is coming..

     

    So what will be my mistake?

    You will have to use XY plots and not the complex plots ( phase and magnitude )

     

    So plot your data as a normal XY plot and then use divide function,
