Abstract

U ovom radu je prikazan pregled pravilnika, opis korištenih materijala i teorija iza proračuna kompozitnih struktura. Također, prikazana je strukturalna razrada monokoka Formula Student bolida. Strukturalna razrada uključuje proračun rasporeda slojeva metodom konačnih elemenata, izradu i ispitivanje uzoraka strukture šasije te proračun jednakovrijednosti odabrane kompozitne strukture u odnosu na pravilnikom definiranu čeličnu cijevnu šasiju. Detaljno su opisani koraci pri odabiru rasporeda slojeva monokoka te proračunati svi dijelovi nove, odabrane kompozitne strukture monokoka. Ispitivanjima uzoraka i proračunima dokazana je sigurnost monokoka i samim time vozača koji će voziti bolid. Konačno, provedena je analiza metodom konačnih elemenata torzijske krutosti šasije i naprezanja šasije kod različitih uvjeta vožnje bolida.

Abstract (english)

This paper presents an overview of the regulations, a description of the materials used, and the theoretical background behind the calculation of composite structures. It also includes the structural development of a Formula Student monocoque chassis. The structural analysis involves the calculation of the layup using the finite element method, fabrication and testing of chassis structure samples, as well as the equivalence analysis of the selected composite structure in comparison to the steel space frame defined by the regulations. The steps taken in selecting the monocoque layer configuration are described in detail, and all components of the newly selected composite monocoque structure are calculated. Through sample testing and analytical calculations, the safety of the monocoque and consequently, the safety of the driver has been demonstrated. Finally, a finite element analysis of the chassis torsional stiffness and stress distribution under various driving conditions was performed.
