Abstract

U ovom radu prikazan je proces zavarivanja čelične konstrukcije buggy vozila te simulacije tog procesa provedene s pomoću programskog paketa Visual Environment. U uvodnom dijelu predstavljen je povijesni razvoj buggy vozila, koja se danas najčešće koriste u automobilskom sportu i za vojne potrebe. Nadalje, opisan je izbor osnovnog i dodatnog materijala za izradu karoserije buggy vozila, TIG postupak zavarivanja i njegovi parametri, poteškoće koje se mogu pojaviti prilikom zavarivanja te načini njihova rješavanja. Također, predstavljen je programski paket Visual Environment i njegovi potprogrami.
U eksperimentalnom dijelu prikazano je laboratorijsko zavarivanje sučeljenog i T-spoja te simulacije procesa zavarivanja s različitim ulaznim parametrima s ciljem pronalaska one kombinacije parametara koja najbolje odgovara raspodjeli temperaturnih polja u zoni utjecaja topline dobivenoj eksperimentalno.

Abstract (english)

This paper presents the welding process of the steel construction of a buggy vehicle and the simulation of the very process conducted using the Visual Environment software package. In the introductory part historical overview of buggy development is given. Today, buggies are mostly used in automobilism and by armed forces. Further, the choice of base and filler materials used to build the chassis of a buggy vehicle is described, as well as TIG welding method employed to unite the metal tubes, its parameters, potential difficulties during the welding process and the ways to overcome them. Finally, the Visual Environment software package is presented together with its subprogrammes.
In the experimental part, the process of welding of fore and T-joint is outlined, followed by the simulation of the process using various inputs aiming to detect the ones corresponding to the experimental findings on the temperature zones distribution in the heat affected zone in the welding area.
