Samenvatting
Basis of standard spectral techniques available for the description and analysis of stochastic processes used in vehicle handling and suspension development, is discussed. Progress towards the present state of the art is indicated by reference to work published over the last 25 years; this work has established that a stationary Gaussion stochastic process does provide a satisfactory basic model for a road surface, and it has now reached a state of considerable sophistication. The development of experimental simulation techniques, based on multivariate stochastic process theory is described and the relationship of such tests to response analysis is explained.
