Abstract
U ovome diplomskom radu prikazan je proces numeričke simulacije i optimiranja steznog spoja remenice i vratila. U početnim poglavljima dane su osnovne informacije potrebne za shvaćanje procesa optimiranja, uvid u problematiku nelinearnosti kontakta među tijelima kao što je stezni spoj te općeniti podaci o steznom spoju. Izrađeni su 3D modeli remenice i vratila koji će poslužiti za proračun i optimiranje. Provedena je analitička i numerička analiza početnog modela steznog spoja remenice i vratila. U prvom djelu pokazala se raspodjela ekvivalentnih naprezanja nastalih djelovanjem dodirnog tlaka u steznom spoju po duljini kontakta i kasnije s dodatnim opterećenjem momentom i silom. Prikazani su rezultati i kontrola konvergencije. Numeričko rješenje uspoređeno je s analitičkim te je provedena numerička simulacija remenice i vratila s jednakom duljinom kontaktnih površina kao dodatna kontrola rezultata. Potvrđena je ispravnost rješenja te je pripremljen podmodel remenice za topološko optimiranje. Za definirane ciljeve i kriterije u sklopu provođenja topološkog optimiranja, dobivena je topološki optimirana remenica koja će poslužiti za daljnju analizu. Model s novom remenicom ponovno je numerički analiziran kako bi se vidjele razlike od početnog modela. Nakon zadovoljavajućih rezultata novog modela, provedeno je optimiranje odzivnom površinom uz odabrane parametre i ciljeve smanjenja mase i naprezanja. Nakon optimiranja postignut je optimalni stezni spoj remenice i vratila.
Abstract (english)
In this thesis, numerical simulation and optimization process has been shown on pulley-shaft shrink fit example. In the first three chapters basic information has been given about understanding optimization process, nonlinear contact behavior such as shrink fit and shrink fit properties. 3D models of pulley and shaft were made, which will be used for analysis and optimization in next chapters. Analytical and numerical analysis has been conducted on the first model pulley-shaft shrink fit. In the first part of analysis, equivalent von Mises stresses due to shrink fit contact pressure results were shown across contact surface, and later force and moment load was included. Results for convergency were shown aswell. Numerical solution was compared to analytical, and also controlled with numerical simulation of the shrink fit with same contact length. The solution correctness was validated and pulley submodel was prepared for topology optimization. For defined goals and criteria, topology optimization was conducted on pulley, which provided new pulley-shaft model. Model with new topologically optimized pulley has been numerically analyzed once more to see differences between first model. After satisfying results in the new model, response surface optimization was carried out with chosen dimensional parameters and minimum mass and limited stress goals. After optimization, optimal solution for pulley-shaft shrink fit was achieved.
