Models of diagnostics and its impact on reliability of motor vehicles

Doktorska disertacija ukazuje na model dijagnostike stanja koji zbog svog istraživačkog karaktera može dovesti do novih naučnih saznanja i metoda praćenja uticaja najvažnijih parametara na pouzdanost vozila, izučavanja ključnih performansi iz oblasti održavanja motornih vozila. Njen cilj je da teorijski i empirijski, kritički, sistematski i kontrolisano definiše model dijagnostike stanja kao i da izvrši izbor optimalnih parametara, radne temperature i pohabanosti ležajeva, a sve u cilju određivanja sigurnosti funkcionisanja sastavnih komponenti motornih vozila. Proces istraživanja modela predstavlja vezu između periodičnosti provere parametara stanja u radu i otkaza sastavnih komponenata motornih vozila. Simulacijom se može prognozirati vremenski trenutak zamene komponenata pre nego što dođe do njihovog otkaza. Dati model je univerzalnog tipa iz razloga što se može primeniti i na složene sisteme, bez obzira na dimenzije komponenti sklopova motornih vozila.PhD dissertation indicates a model of state diagnostics, which due to its research nature, could lead to new scientific knowledge and methods of monitoring the impact of the most important parameters on vehicle reliability, the study of key performance in the field of maintenance of motor vehicles. Its aim is to theoretically and empirically, critically, systematically and in a controlled way define the model of conditions diagnostic and to make the selection of optimal parameters, operating temperature and wear of bearings, all for the purpose of determining the security of functioning of the parts and components of motor vehicles. The research process of a model represents the relationship between the periodicity of testing parameters of the operating mode and cancellation of integral components of motor vehicles. The simulation can predict time for replacement of components before they cancel. The present model is of a universal type because it can be applied to complex systems, regardless of the dimensions of the components of motor vehicles
