Abstract

Studenti Fakulteta strojarstva i brodogradnje u Zagrebu redovito sudjeluju a natjecanju Formula Student. Cilj natjecanja je konstruirati i izraditi bolid koji će se natjecati. Prilikom razvoja bolida nezaobilazni su simulacijski alati koji omogućuju razvoj boljeg bolida uz manju upotrebu novčanih sredstava, a u sklopu ovog rada optimirani su parametri simulacijskog modela bolida. Opisani su parametri koji imaju najveći utjecaj na dinamičko ponašanje bolida i definirani su promjenjivi parametri čijim se optimiranjem mogu postići bolji rezultati na dinamičkom dijelu natjecanja Formula Student. Prikazan je postupak izrade virtualnog vozača na temelju mjerenja vožnje stvarnog vozača izrađenom stazom. Parametri se definiraju na temelju preklapanja dijagrama brzine i bočnog ubrzanja u ovisnosti o prijeđenom putu bolida. Prikazane su sve izmjene na modelu bolida Strix-R (sezona 2018.) u odnosu na bolid Strix (sezona 2017.) te način implementacije promjena u simulacijski model bolida u programu CarSim. Nakon implementacije promjena provedeno je optimiranje promjenjivih parametara bolida za postizanje najboljih rezultata u dinamičkim disciplinama natjecanja Formula Student. Na temelju optimiranja definirane su preporuke za postavke bolida u različitim disciplinama natjecanja Formula Student.

Abstract (english)

Students on a Faculty of Mechanical Engineering and Naval Architecture are regularly involved into Formula Student competition. Goal of competition is to design and make race car. Simulation tools are required in the development phase of project, because they are cheap when compared with prototype production since the budget of project is limited. In this thesis parameters with biggest influence on dynamical behavior are described. Variable parameters are defined which values will be optimized to achieve best results on dynamic events of Formula Student competition. Process of defining virtual driver parameters based on real drive on a test track is described. Parameters are defined based on a comparison of speed and lateral acceleration graphs. All changes on formula student racing car Strix (2017.) to Strix-R (2018.) are described. Optimization of variable parameters for all dynamic events is described. At the end recommendations of suspension system settings are defined to give the best results on Formula Student competition.
