I mean accel versus frequency. I obtained this data by taking FFT of time domain in-situ manufacturer data from a test where he mounted accels to hard points on the chassis of vehicle.
So now i have two curves. 1)freq./g**2 from random test we ran. 2) freq/g curve from vendor.
Now to compare the two do I just look at what happens at resonance of the part mounted to the chassis (which i make) and use Miles equation? Then see which gives the higher loading?
I am sure there I cannot just make a head to head comparison but only look at resonance to see if there was an overtest situation.
