Abstract
Inovativnim rješenjima, odnosno uporabom inovativnih materijala, nastoji se ostvariti jedan od ciljeva kojemu teže svi timovi koji su sudionici Formula Student natjecanja - smanjenje ukupne mase natjecateljskog vozila. Pogonske osovine, odnosno vratila – poluvratila, element su kod kojega je ostvariva značajna ušteda na masi prelaskom sa čelika na kompozitni materijal – ugljičnim vlaknima ojačanu smolu (eng. CFRP – Carbon Fiber Reinforced Polymer). Analitički je, pomoću relacija koje slijede iz teorije ljusaka i mehanike kompozitnih materijala, a iz zadanih polaznih veličina, određen srednji polumjer i broj slojeva koji su potrebni da kompozitna cijev izrađena od ugljičnih vlakana (T700) i epoksidne smole (DT120) zadovoljava kriterije popuštanja karakteristične za kompozitne materijale. Fleksijska kritična brzina vrtnje također je analitički određena. Zatim je koristeći programski paket Abaqus/Standard napravljen model i provedena statička numerička analiza metodom konačnih elemenata (MKE) kojom su potvrđene analitički dobivene dimenzije cijevi. Nakon toga, analitički su određene a potom i numerički potvrđene potrebne dimenzije prirubnica – nosača tripoidnih križeva. Predstavljena su moguća rješenja spajanja cijevi i prirubnica. Odabirom lijepljenog spoja kao najpovoljnije opcije, pomoću analitičkih su izraza određene potrebne dimenzije ovog spoja i samih prirubnica, odnosno elemenata koji prenose torzijski moment sa cijevi na tripoidne križeve i obrnuto. Konačno, naprezanja u spoju također su analizirana MKE metodom koristeći programski paket Abaqus/Standard.
Abstract (english)
With innovative solutions, by using innovative materials, it is tried to achieve one of the goals all teams participating in a Formula Student competition are striving for – reducing the overall mass of the competing vehicle. Propelling shafts, i.e. halfshafts, are elements that offer a significant mass reduction by altering the material they are made of from steel to a composite material – carbon fibre reinforced polymer (CFRP). Firstly, from input data, using relations based on theory of shell structures and classical lamination theory, the mean radius and the number of plies in a composite tube made of carbon fibre (T700) and epoxy resin (DT120) have been analytically determined so that the composite materials failure criteria are satisfied. Flexural critical speed has also been analytically determined. After that, using the Abaqus/Standard software, a model was created and a numerical static analysis using finite element method (FEA) was performed in order to confirm the analytically obtained results. Then dimensions of the steel adherends were analytically obtained and then numerically validated. The possible solutions for connecting the tube with adherends were presented. After choosing the adhesive joint as an optimal solution, using analytical relations, dimensions of the joint itself and the steel adherends, (i.e. the elements that are transferring the torsional load from the composite tube to the tripoid joints and vice versa) have been determined. Finally, stresses in the adhesive joints were analysed using FEA in Abaqus/Standard as well.
