Abstract

U sklopu ovog rada, zadatak je bio provesti proračun za odabir prijenosnog omjera za Formula student bolid te validacija istog putem simulacija u računalnom alatu AVL VSM. Proračun je baziran na 2D modelu koncentrirane mase i modelu bicikla. Potrebni parametri su geometrija bolida, parametri aerodinamičkog paketa, momentna karakteristika elektromotora te model gume. Ograničenje samog proračuna je jednostavan model vozila u kojem nisu promatrana prigušenja tijekom ubrzanja. Iz tog razloga su provedene simulacije različitih prijenosnih omjera pomoću VSM-a u kojem je bilo potrebno definirati model vozila, staza procedure Acceleration i model vozača. U samom radu je detaljno opisan tijek proračuna, svi korišteni parametri te je opisan postupak simuliranja Formula student procedure Acceleration. Konačni rezultati su komentirani te je odabran prijenosni omjer 12.

Abstract (english)

As part of this work, the task was to carry out calculations for the selection of the transmission ratio for the Formula student car and its validation through simulation in the computer tool AVL VSM. The calculation is based on a 2D concentrated mass model and a bicycle model. The required parameters are the geometry of the car, the parameters of the aerodynamic package, the torque characteristic of the electric motor and the tire model. The limitation of the calculation itself is a simple vehicle model in which damping during acceleration was not observed. For this reason, simulations of different transmission ratios were carried out using VSM, in which it was necessary to define the vehicle model, the path of the Acceleration procedure and the driver model. The paper itself describes the calculation process in detail, all the parameters used, and describes the procedure for simulating the Formula student procedure Acceleration. The final results were commented and a transmission ratio of 12 was chosen.
