Abstract
U ovom diplomskom radu razmatrana je primjena procesa topološkog optimiranja, prvenstveno minimum compliance design pristup, u razvoju komponenata ovjesa bolida Formule Student. Odabrana komponenta na kojoj je proveden postupak topološkog optimiranja je nosač prednjeg kotača bolida Formule Student. Od više dostupnih programskih paketa koji omogućavaju rješavanje problema topološkog optimiranja odabran je Abaqus CAE. U prvome dijelu diplomskog rada opisani su algoritmi topološkog optimiranja i njihove matematičke osnove. Uz to prikazana su rješenja benchmark problema iz literature i uspoređena s dobivenim rješenjima pomoću programskog paketa Abaqus CAE. Nadalje, prikazani su utjecaji parametara optimizacije na dobivena rješenja na jednostavnijim primjerima iz literature. Na taj način izvršena je verifikacija programskog paketa kojom se pokazalo kako je Abaqus CAE adekvatan za rješavanje problema topološkog optimiranja. U drugom dijelu diplomskog rada opisan je postupak izrade numeričkog i optimizacijskih modela prednjeg nosača kotača bolida Formule Student. Postupak izrade numeričkog modela sastoji se od nekoliko koraka: izrada CAD modela inicijalne konstrukcije kojom je definirana domena rješenja optimizacijskog procesa, analiza rubnih uvjeta i opterećenja koja djeluju na prednji nosač kotača te diskretizacija CAD modela konačnim elementima. Koraci postupka izrade optimizacijskog modela su definiranje funkcija cilja i ograničenja jednakosti i nejednakosti te definiranje geometrijskih ograničenja. Ukupno su analizirana tri optimizacijska modela od kojih prvi ima tri različite varijante. Svaki od optimizacijskih modela proveden je za četiri odabrana slučaja opterećenja izvedena iz rezultata simulacija dinamike bolida dobivenih programskim paketom CarSim. Za svaki od optimizacijskih modela nosača kotača prikazani su rezultati. U posljednjem dijelu rada opisan je postupak konstrukcije konačnog modela prednjeg nosača kotača bolida Formule Student na temelju dobivenih rezultata i dana je usporedba sa nosačem kotača prethodnog bolida Strix.
Abstract (english)
This master thesis considers the application of topology optimization method in development of components of the suspension of the Formula Student race car primarly using minimum compliance design approach. Selected component on which topology optimization will be conducted is the upright of the front wheels of the Formula Student race car. Selected software that is capable of solving topology optimization problems is Abaqus CAE because of its reliability and availability. In the first part of thesis basic topology optimization algorithms and their mathematical basis are described. In addition, solutions of benchmark problems from literature are presented and compared with solutions obtained using Abaqus CAE software. Impacts of optimization parameters on solutions obtained solving simpler examples from the literature are also explored and presented in this part of thesis. Process of defining numerical and optimization models of the front wheels upright of the formula Student race car is described in second part of thesis. Numerical model is defined by steps as followed: development of CAD model of the initial design of the front wheel upright which defines solution domain of the optimization model, analysis of boundry conditions and loads acting on the front wheel upright and discretization of CAD model with finite elements. The optimization model is defined by objective function and constraints of equality and inequality and with geometric constraints. Total of three optimization models, one of which has three different variants, are analyzed in this thesis. Four selected load cases derived from data obtained with CarSim software have been implemented in each of optimization models. Conducting simulations and presentation of results follows after defining numerical and optimization results. In the last part of thesis, design of the final model of the front wheel upright of the Formula Student race car using obtained results is described and compared with the front wheel upright of the previous version of the Formula Student race car named Strix.
