The paper deals with the considerations related to the basic properties and application of primarily aluminum alloys and composite materials for different purposes with the focus on the automotive industry. Through the description of the basic characteristics of aluminum alloys, the starting points for their application in different technical systems are given. On the other hand, the advantages and disadvantages of the use of certain aluminum alloys, along with the guidance and compounds and elements whose use is further enhanced and enriched by aluminum alloys, are predominantly presented. The application of aluminum alloys in the automotive industry, as well as the particular types of aluminum based materials used for individual aggregates and circuits of motor vehicles, as well as their behaviour in different operating modes are imposed as a key chapter of the work. Ultimately, the advantages that are primarily achieved with the vehicle are obtained by the use of aluminum alloys and composites, with the conclusion that there is still space in the field, further improvement of the characteristics of aluminum alloys, and in the field of expansion of the diapason of their application.
Postojeći modeli upravljanja održavanjem tehničkih sistema imaju za cilj obezbeđenje željene pouzdanosti i raspoloživosti sistema, po mogućnosti uz što manje troškova. Novi koncepti, koji se sve više primenjuju u svim oblastima života, zasnovani su na riziku. Takav pristup je moguć i poželjan i u području teorije i inžinjerstva održavanja tehničkih sistema i vojnotehničkih sistema. U ovom radu navedena su pojmovna određenja održavanja tehničkih sistema, modela upravljanja održavanjem i strategija održavanja. Nakon toga dat je pregled strategija i modela upravljanja održavanja tehnički sistema, njihovi šematski prikazi i međusobna upoređivanja, kao i trendovi u upravljanju održavanjem tehničkih sistema, čijom bi se primenom možda mogle ostvariti uštede u održavanju, kako tehničkih, tako i vojnotehničkih sistema.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
