20.500.12556/DKUM-43558 Visokotrdnostna jekla v vozilih - uporaba reševalnega orodja za razrez visokotrdnostnih jekel v vozilih High - strength steels in vehicles - use of rescue tools for cutting high - strength steel in vehicles Visokotrdnostna jekla se v zadnjem obdobju v vedno večji meri uporabljajo v avtomobilski industriji. Mehanske lastnosti teh jekel namreč proizvajalcem omogočajo, da izdelujejo veliko lažja, predvsem pa varnejša in ekološko bolj dovršena vozila. To proizvajalcem omogoča, da izdelujejo osnovne sestavne dele vozila (karoserijo, platišča, roke …) trše in bolj odporne. To pomeni, da morajo biti narejeni iz visokotrdnostnih jekel. Le-ta imajo visoko trdnost in se veliko boljše obnašajo ob trku. Jeklo se veliko manj deformira, kar pomeni, da osnovna karoserija in notranjost kabine vozila ostaneta bolj nepoškodovana in s tem varnejša za voznika. Sodobna avtomobilska industrija temelji le na tem, da izdelujejo vozila, ki bodo ob trku varnejša za ljudi v avtomobilu. Ta jekla pa predstavljajo izredno težavo za gasilce, ki posredujemo ob prometnih nesrečah, saj za zdaj še ni bilo veliko povedanega in raziskanega o reševanju v primeru tovrstnih vozil. Teoretični razlagi v zaključku dela sledi še praktični primer in analiza razreza visokotrdnostnih sestavnih delov vozila. High strength steels have been used increasingly in the automotive industry in recent years. The mechanical properties of these steels allow manufacturers to produce much easier, and above all safer and more ecologically sophisticated vehicles. This allows manufacturers to produce the basic components of the vehicle (bodyshell, wheels, hands ...) harder and more resistant. It means that they must be made of high strength steels. Steels have high strength and behave much better in a collision. Steel is much less deformed, which means that the basic bodyshell and interior of the vehicle remain more intact and thus safer for the driver. The modern automobile industry is based only on the fact that they make vehicles, which will be safer for the people in the car collision. These steels represent an extreme difficulty for firefighters, who serve in road accidents, because for the moment there was not much said and researched about rescuing in case of such vehicles. The theoretical interpretation in the end of the thesis is followed by a practical example and analysis of cutting high strength components of the vehicle. preoblikovanje visokotrdnostna jekla v vozilih reševalno orodje sile pri preoblikovanju transformation high strength steels in vehicles rescue tool forces in transformation true true false [A.
