“…A frequency based concept called ''Effective Road Profile'' [12] has been developed for the automotive industry. This concept is used to find the laboratory four-poster shake rig drive-files that produce the inputs for two vehicles with different dynamic properties travelling over the same road profile.…”

A time domain simulation error method is presented in the following article for estimating the excitation of structural systems from local operational responses. The present study focuses on the case in which the location of the excitation is known a priori, as it is for the interaction of the road profile and the tyre patch for an automotive vehicle. The road profile is parameterized into coefficients using truncated sets of base functions which greatly reduce the number of unknowns in the resulting non-linear optimization problem. A complex non-linear model of a ground excited vehicle is utilized to illustrate the applicability and performance of the method.
