20.500.12556/DKUM-37890 Numerična analiza ojnice hibridne sestave Numerical analysis of hybrid connecting rod V praksi se pojavlja čedalje več izdelkov, narejenih iz polimernih kompozitov, vzporedno pa narašča tudi potreba po numeričnih analizah le-teh. Izdelki iz polimernih kompozitov imajo ortotropne mehanske lastnosti, katere pa so se v preteklosti pri mehanskih analizah dostikrat zanemarjale ali poenostavljale, posledica česar so bili slabi rezultati numeričnih analiz. Diplomsko delo predstavlja pomen upoštevanja ortotropnih mehanskih lastnosti in orientacije armiranih vlaken pri mehanskih analizah na konkretnem primeru ojnice hibridne sestave. Prikazani so poteki numeričnih analiz z ali brez upoštevanja ortotropnosti in orientacije, rezultati pa so primerjani z eksperimentalnimi testi. Diplomsko delo predstavlja tudi vpliv tehnoloških dejavnikov na rezultate mehanskih analiz in možnost optimizacije le-teh. An increasing number of products are made from polymer composites, which in turn increases the need for numerical analysis of these. The products from polymer composites have orthotropic mechanical properties, which have been often overlooked or simplified in the past, resulting in poor results of numerical analyses. This graduation thesis presents the meaning of orthotropic mechanical characteristics and orientation of reinforcing fibers in mechanical analyses on an actual study case of a hybrid connection rod. It follows the course of numerical analyses with or without taking into account the orthotropic characteristics and orientation, while the results are compared with experimental tests. The thesis also studies the influence of technological factors on the results of mechanical analyses, and the options for their optimization. hibridni izdelki kompoziti polimeri steklena vlakna metoda končnih elementov simulacije brizganja Abaqus Moldflow hybrid products composites polymers fiberglass finite element method injection molding simulation Abaqus Moldflow true true false [M.
