Original Abstract

The authors use the mathematical model of the vehicle suspension to simulate the diagnostic procedure of the EUSAMA methodology. Simulations on large dataset of vehicle chassis are calculated to identify the causes of false-negative evaluation of car condition often found in the cars that are in good technical shape. It is proved that the most important cause of the methodology failure is the concurrence of current trend to use stiff car tyres and a high excitation stroke of currently used test rigs. Such high amplitudes of excitation do not correspond to the excitation from modern roads. Then, the authors verify the effects of non-linear characteristics of the damper and tyre stiffness on the results obtained by simulation diagnostic tests. This paper introduces the adjustments of the EUSAMA methodology, which should eliminate a growing set of tests with contradictory diagnosis results.
