Abstract (Croatian)

Zemljani transport putnika i materijalnih dobara putem tračničkih vozila iznimno je efikasan i efektivan. Pošto se odvija kroz naseljena i nenaseljena mjesta izrazito je bitno da proizvedena tračnička vozila budu zadovoljavajuće kvalitete. Strogi zahtjevi za kvalitetu tračničkih vozila postavljeni su prvenstveno zbog očuvanja života i spriječavanja nesreća u naseljenim mjestima. Sekundarni razlozi su materijalne uštede, bilo na održavanju, energentima ili drugim troškovima koji nastaju prilikom eksploatacije vozila. Tračnička vozila mogu se podijeliti na lokomotive i vagone, dok se vagoni mogu dalje podijeliti na putničke i teretne. U okviru ovoga rada razmatraju se teretni vagoni. Pošto su vagoni složeni sklopovi, za potrebe rada razmatra se jedna njegova cjelina - osovinski sklopovi, tj. kvaliteta izrade osovinskih sklopova. Teoretski dio rada izlaže: (i) definicju kvalitete; (ii) osnove upravljanja kvalitetom, te sustave i smjernice upravljanja kvalitetom; (iii) koncizan pregled tračničkih vozila; (iv) zahtjeve za kvalitetu tračničkih vozila, poglavito za teretne vagone; i (v) osovinske sklopove za teretne vagone. Studija slučaja, praktični dio rada, izlaže procjenu sposobnosti procesa izrade osovine za osovinske sklopove teretnih vagona

Abstract

Land transport of passengers and material goods via railway vehicles is highly effective and efficient. Since railways pass through populated as well as unpopulated areas, it is of utmost importance that manufactured railway vehicles are of satisfactory quality. Strict quality specification of railway vehicles are set primarily for protection of human lives and accident prevention. Secondary reason are material savings on maintenance, fuel and other expenses that result from vehicle exploitation. Railway vehicles can be divided into locomotives and wagons, while wagons can be divided into passenger cars and freight wagons. This master thesis deals with freight wagons. Since aforementioned wagons are complex systems, specific element of the system is examined - wheelsets, especially freight wagon axles. Theory presented in master thesis is as follows: (i) quality definition; (ii) basics of quality management, including systems and frameworks; (iii) concise overview of railway vehicles; (iv) quality specifications of railway vehicles, especially of freight wagon; and (v) freight wagon axles. Case study, a practical part of master thesis, presents process capability analysis of manufactured freight wagon axles.
