Diagnostic Vehicles as a Basis Maintenance

Abstract

The special problem in the maintenance of motor vehicles is the objective identification of the state of vital components and definition of their replacement period or revitalization. Reliability of composite systems and its diagnostic are the main topic of current themes concerning vehicles. Application of diagnostic methods in order to define technical condition of motor vehicle is important, esp. in dynamic regime. For example, method of diagnostics of braking – according to curve, change in brake force on wheels, diagnostics of motor sus – according to indicator diagram, diagnostics of different mechanisms according to parameters of vibroacoustic process etc. This paper gives possibilities applications objective diagnostic methods, and it is implemented for the analysis of the state of a motors vehicle.

U održavanju motornih vozila poseban problem predstavlja objektivno utvrdjivanje stanja vitalnih komponenata i definisanje perioda njihove zamene, odnosno revitalizacije. Primena dijagnostičkih metoda radi utvrđivanja tehničkog stanja motornog vozila je značajna, naročito u dinamičkim režimima. Na primer: metoda dijagnostike kočenja - prema krivoj promene kočione sile na točkovima, dijagnostika motora sus - prema indikatorskom dijagramu, dijagnostika različitih mehanizama prema parametrima vibroakustičkih procesa i td. Težište sadašnjih tema u oblasti vozila su na pouzdanosti složenih sistema i njihovoj dijagnostici. U radu su date mogućnosti primene objektivnih metoda dijagnostike pri utvrdjivanju stanja motornih vozila.
