Abstract

U sklopu ovog završnog rada razvijen je programski alat za simulaciju i analizu performansi vozila na temelju jednostavnog matematičkog modela, koji opisuje vozilo pomoću seta osnovnih parametara koji utječu na performanse vozila. Svrha ovoga alata je analizirati utjecaj osnovnih parametara na performanse vozila te na temelju rezultata simulacija provesti evaluaciju različitih koncepata u ranoj fazi razvoja Formula Student bolida.

U uvodnom dijelu rada opisano je Formula Student natjecanje te potreba za ovakvim programskim alatom u ranoj fazi razvoja bolida. Detaljnije su opisane dinamičke discipline natjecanja te princip bodovanja u tim disciplinama. U sljedećem poglavlju opisani su osnovni parametri vozila koji utječu na performanse vozila, uvedena ograničenja i pretpostavke pri korištenju takvog modela te su raspisane jednadžbe koje čine matematički model. Glavni dio rada čini prikaz razvijenog programskog alata i mogućnosti koje nudi. Prikazan je proces modeliranja vozila, provedbe simulacija i analize dobivenih rezultata te je dana usporedba razvijenog programskog alata s programskim alatom OptimumLap temeljenim na sličnom matematičkom modelu. Vrednovanje programskog alata provedeno je usporedbom rezultata s rezultatima dobivenim simulacijama u komercijalnom programu CarSim, koji sadrži mnogo kompleksnije matematičke modele te simulira dinamiku vozila s vrlo velikom točnošću. U završnom dijelu rada provedena je evaluacija različitih koncepata pri razvoju ovogodišnjeg bolida FSB Racing Team-a koristeći vlastiti programski alat i programski alat OptimumLap.

Abstract (english)

The goal of this bachelor thesis was to develop a program for simulation and analysis of vehicle performance, based on a simple mathematical model which describes a vehicle as a set of basic parameters which influence vehicle performanse. The purpose of this program is to analyze the influence of theese parameters on performance and to perform an evaluation of different concepts in early stages of Formula Student race car development.

At the beginning of the thesis, Formula Student competition is described, and the need for this type of program in early stages of race car development is explained. Detailed description of dynamic disciplines is given as well as and scoring principles for theese discplines. The next chapter describes the basic parameters which influence vehicle performanse, limitations and assumptions imposed by using this type of model and the equasions of which the mathematical model consists. The main part of the thesis is the presentation of the developed program and its features. The process of vehicle modelling and simulation, as well as the analysis of the obtained results is shown, and the comparison of a developed program to a similar program called OptimumLap is given. Evaluation of a developed program is conducted by comparing the results with those obtained in a commercial program CarSim, which incorporates mathematical models of much higher complexity, thus simulating vehicle dynamics with very high accuracy. In the final part of the thesis, the evaluation of different concepts in development of FSB Racing Team's new race car, using both programs, is shown.
