(vii) short-time Fourier transformed roll acceleration.
By comparing each class with each other, it emerges that the peak-to-peak value of pitch and roll acceleration are mainly responsible to separate events, which occur on
Furthermore, potholes and manhole covers are dividable through the maximum RMS of the roll acceleration for the frequency range 15 to 25 [m.sup.-1].
(i) RMS of the roll acceleration for frequency range from 5 to 15 [m.sup.-1] on average
where [??] is the body roll acceleration
, [h.sub.0] is the height of the vehicle's center of gravity (CG) standing above the ground level, h is the distance between the vehicle CG and the assumed roll axis, T is the width of the vehicle track, and [DELTA]h and [DELTA]T are the deformations of suspensions and tires.
