20.500.12556/DKUM-79794 Trdnostna analiza in preračun dobe trajanja udarne igle v pištoli AREX DELTA diplomsko delo Strength analysis and lifetime calculation of the firing pin in the pistol AREX DELTA Diplomska naloga obravnava postopke, ki so potrebni, da lahko približno napovemo dobo trajanja udarne igle pištole, ki je primerljiva z rezultati mehanskih eksperimentov. Postopki, ki smo jih opravili, so priprava in izvedba eksplicitnih dinamičnih simulacij, izbira ustreznega računskega modela za izračun dobe trajanja in pregled vplivnih parametrov na dobo trajanja. Kljub upoštevanju določenih poenostavitev v modelu, so rezultati pokazali dobro ujemanje eksperimentov in numeričnih simulacij. Končna ugotovitev predstavlja dogajanje med in po udarcu ter ustreznost uporabljenega materiala igle. The work is focused on the methods needed to approximately predict the lifetime of a firing pin that is comparable to mechanical experimental results. The following steps are: performing explicit dynamic simulations, choosing the correct computer model for the lifetime calculation and analysis of factors that affect the firing pins lifetime. Although some model simplifications have been used, results have shown good comparison between experiments and numerical simulations. In conclusions, the work describes the occurring events during and shortly after impact, and the suitability of chosen materials. pištola udarna igla trdnostna analiza dinamične simulacije doba trajanja pistol firing pin strength analysis dynamic simulations lifetime true true false [E.
