ABSTRACT
A process is described that allows the identification of the road profile traversed by a tractor based only on acceleration signals measured in the field. The objective of this identification process is to obtain a field path profile that, when simulated, produces accelerations in the tractor as close as possible to those generated by the original profile, thereby causing similar damage values to the structure of the tractor. This process requires an accurate multibody system model of the vehicle with a sophisticated tire model. Under these considerations a method has been developed making it possible to invert the dynamic problem and to determine the field path profile, which can subsequently be used for simulations of arbitrary tractors.
