20.500.12556/RUL-138768 Napetostna analiza stabilizatorja Formule Študent pri dinamičnih obremenitvah med vožnjo Tension analysis of the Formula Student stabilizer at dynamic loads while driving Stabilizator predstavlja enega od ključnih sestavnih elementov vozila, ki prenaša deleže obremenitve z ene strani podvozja na drugo stran. Glavni cilj naloge je bila numerična analiza napetostnega stanja glavnega kosa stabilizatorja, t.i. lista stabilizatorja, na sprednjem in zadnjem delu podvozja Formule Študent. Geometrijski sestav Formule je bil modeliran v programu NX, ter nato kot CAD model uvožen v program Adams View. Tam so bile definirane medsebojne relacije sestava in nato opravljene simulacijske analize obremenitev za različne scenarije dinamične obremenitve, ki jih lahko primerjamo s situacijami, ki se pojavijo pri vožnji formule na tekmovanjih. Vsak scenarij je imel več orientacij lista stabilizatorja, kar vpliva na obremenitve na le-tem in na karakteristiko vožnje. Izvede se primerjalna analiza napetosti v obeh listih stabilizatorja glede na njuno orientacijo. Na koncu so bili pridobljeni rezultati ovrednoteni glede na utrujevalne karakteristike materiala, iz katerega je izdelan list stabilizatorja. The stabilizer is one of the key components of the vehicle, which transfers load fractions from one side of the chassis to the other. The main goal of the thesis was the numerical analysis of the stress state of the main stabilizer piece, the stabilizer flappy, on the front and rear of the chassis of the Student Formula. The geometric composition of the formula was modeled in the NX program, and then imported into the Adams View program as a CAD model. There, the mutual relations of the parts were defined and simulation load analyses were performed for different dynamic load scenarios, which can be compared with the scenarios that occur when driving a formula in competitions. Each scenario had several orientations of the stabilizer’s flappy, which affects the loads on it and the driving characteristics. A comparative analysis of the stresses in both stabilizer’s flappys with respect to their orientation was performed. In the end, the results were obtained and evaluated according to the fatigue characteristics of the material from which the stabilizer sheet is made.
