Original abstract

Abstract: The article deals with recent failures of the EUSAMA methodology which is used for non-destructive testing of the car chassis without disassembling. On simulated data, there is performed an analysis of false-negative evaluation of car condition which occurs often on cars in actually good technical shape. High tire stiffness in combination with small axle load are identified as main causes of the methodology failures. Such combination of technical features is common for car chassis designed according contemporary trends in automotive industry. Adjustment of the too high excitation stroke is suggested as possible future recourse. Therefore the testing conditions should comply with contemporary quality of the road surfaces.
