Hi! I joined thanks to a member that recommended
First of all excuse my english!!!
I know the basics of vehicle dynamics and Im learning a lot with rFactor data acquisition (motec).
I was doing in-line testing (measuring rfactor model downforce and cd) and I looked at this:
I would like to understand a bit more about it. I read what fft is and I quite understand it but I not sure about the units, because I have seen a "real life" fft suspension graphic that is mm vs. Hz and this is not.
What unit is power spectrum density? What is window type hamming (it changes a lot the graphic)? What conclusion I get fromm this picture? (it is straight line testing of a formula vee but with wings in monza)
