Integral Transformations of Road Profile Excitation Spectra for Variable Vehicle Speeds

As a consequence of variable traffic speeds, vehicles are excited by road profile processes having spectral densities differing from those known from the literature, although stationary in order two. This phenomenon has to be reckoned with primarily in the dynamic design of vehicles operating mostly in cities. A method has been presented for the numerical construction of distorted road profile spectra for variable travel speeds, using integral transformation methods, of use in the dynamic design of vehicles.
