The team I'm currently working for is trying to compare bushings with different durometer ratings in the front suspension using single axis(z) accelerometer data during curb impacts. The current problem at hand is that the amplitude recorded is close to one g or two and noisy at curb impacts. I did a FFT and PSD analysis to check that none of the contributing frequencies match the resonance frequency of the accelerometer. This was followed by Inverse FFT of that signal.
Now my team thinks of forming some kind of force distribution using the denoised data.
Is it a good experiment using accelerometer data to compare the two different durometer bushings? For some reason, I think there is a better way to compare the ride quality using the different bushings.
The two accelerometers are attached below the seat and on the link connecting bushing to the base.
