The response of vehicle components to random road surface undulations

Standard techniques of random vibration analysis have been applied to the problem of determining the response of vehicle components to random road surface undulations. A simple road classification method, which will typify the general terrain inputs to vehicles is proposed and is based on the knowledge of the spectral density of any 1ongitudinal track. Finally, this work introduces a novel technique for simulating in the laboratory the response of a. vehicle to road profile excitation. Three analytical models of increasing complexity are used to describe the road surface roughness. The first considers the road as consisting of a cylindrical surface which can be defined by means of a single longitudinal track of (x), treated as a member function of a Gaussian random process.
