Abstract
Tema ovog diplomskog rada je izvršiti analizu naprezanja motociklističke kacige pri udarnom opterećenju. Računalno modeliranje geometrije izvršeno je pomoću programa SolidWorks, a numerička analiza programom Abaqus/Explicit. Na početku rada iznesen je pregled zaštitne motociklističke opreme, te je opisana konstrukcija kacige. Prilikom modeliranja glave korištene su CT snimke za dobivanje geometrijske reference za model lubanje. Validacija numeričkog modela glave izvršena je usporedbom rezultata s numeričkim i eksperimentalnim rezultatima dostupnim u literaturi. Ispitivanje apsorpcije energije udarca provedeno je s početnim uvjetima propisanim standardom za što su su korištene ljuske načinjene od različitih materijala. Popuštanje kompozitnog materijala određeno je prema Hashinovom kriteriju popuštanja.
Abstract (english)
The subject of this thesis is to perform a stress analysis of a motorcycle helmet under impact load. Computor aided design of the geometry was done using SolidWorks, while the numerical analysis was performed in Abaqus/Explicit. An overview of motorcycle protective gear and the design of the helmet was described in the introduction of the thesis. CT scans of the skull were used to obtain the realistic geometry, which was used as a reference for the CAD model of the skull. Validation of the head numerical model was done by comparison with numerical and experimental results from the literature. Impact energy absorption test was done with the initial conditions prescribed by standards, while shells made of different materials were used in the numerical analyses. Failure of the composite material was modelled using the Hashin’s failure criteria.
