Abstract

Računalne simulacije neizostavan su dio pri razvoju bolida Formule Student, omogućujući postizanje optimalnih rezultata kako u dinamičkim, tako i u statičkim testovima, kroz predstavljanje rezultat simulacija koji podržavaju donesene konceptualne odluke. Cilj ovoga rada je razviti jednostavni model za dinamičku simulaciju analize vremena kruga. U uvodnom dijelu rada dan je opis simulacije vremena kruga te su prikazani postojećih simulacijski alati. Nakon toga, prikazane su teorijske podloge za izradu modela. Model je izrađen korištenjem Matlab/Simulinka, a jedini potreban ulaz u model su GPS koordinate staze na kojoj se želi provesti simulacija. Unutar Matlab-a postavlja se matematički model staze i vozila te se kreira ciljani profil brzine, koji služi kao ulaz u dinamičku simulaciju. Na kraju, rezultati dobiveni izrađenim modelom uspoređeni su s rezultatima dobivenim ponavljanjem iste simulacije u software-u AVL VSM.

Abstract (english)

Computer simulations are essential in developing Formula Student cars, helping achieve optimal results in dynamic and static tests by presenting data that supports conceptual decisions. The aim of this paper is to develop a simple model for dynamic lap time simulation. In the introductory part of the paper, a description of the lap time simulation is given, and the existing lap time simulation softwares are presented. After that, the theoretical description for the creation of the model is given. The model was created using Matlab/Simulink, and the only required input into the model is the GPS coordinates of the track on which the simulation is to be carried out. Inside Matlab, a mathematical model of the track and the vehicle is set up, and a target speed profile is calculated, which serves as an input to the dynamic simulation. In the end, the results obtained by the created model were compared with the results obtained by repeating the same simulation in the AVL VSM software.
