Originální abstrakt

The article deals with recent failures of the EUSAMA methodology which is used for non-destructive testing of the car chassis without disassembling. Using simulated data, we perform an analysis of false-negative evaluation of car condition which occurs often on cars, which are actually in good technical shape. Suggested analysis is able to evaluate the changes introduced to the testing methodology directly on this particular group of chassis designs. The excitation stroke is identified as one of the main causes of methodology failure. The authors suggest that the stroke does not match the roughness profile of current roads. The authors propose certain adjustments of the EUSAMA methodology which should eliminate growing set of tests with contradictory diagnosis result. Suggested adjustments are tested by simulation as well. These adjustments involve changes either in software or hardware section of methodology. Significantly, the proposed adjustments can be easily applied to most EUSAMA testers already produced. However, it is assumed that the suggested methodology changes will be so significant, that new methodology cannot be labeled as EUSAMA anymore.
