Abstract

Za tekmovalno sezono 2020 smo pri ekipi Superior Engineering Univerze v Ljubljani zasnovali in izdelali dirkalnik za tekmovanja v seriji Formula Student. V tej sezoni smo si prvič v zgodovini ekipe zadali cilj analizirati in izmeriti togost primarne strukture dirkalnika Tabaluga. V ta namen smo pripravili simulacijski model primarne strukture v programu Abaqus in na njem simulirali najbolj tipično obremenitev, ki jo primarna struktura izkusi in s tem pridobili simulirano vrednost togosti. Po tem smo zasnovali napravo za eksperimentalno merjenje togosti, ki smo jo tudi pomerili na samem dirkalniku. Ugotovili smo, da je dejanska togost za približno 25-35 % manjša od simulirane, kar lahko pripišemo nekaterim izdelovalnim tehnikam primarne strukture in tudi natančnosti simulacijskega modela.

Secondary title: Stiffness measurment of the primary structure of a Formula Student race car
Secondary abstract: The team Superior Engineering of the University of Ljubljana has designed and manufactured a race car for competitions in the 2020 season of the Formula Student series. In this season, we set a goal to analyze and measure the stiffness of the primary structure of the car Tabaluga for the first time in the history of the team. For this purpose, we prepared a simulation model of the primary structure in the simulation software Abaqus and simulated the most typical load case experienced by the primary structure and thus obtained a simulated stiffness value. This led to us designing a rig for experimental measurement of the stiffness and using it to test said stiffness. We found that the actual stiffness is about 25 - 35 % lower than the simulated counterpart, which can be mostly attributed to some manufacturing techniques of the primary structure as well as the accuracy of the simulation model.
