MODELLING AND STATIC ANALYSIS OF AUTOMOBILE WHEEL RIM USING FINITE ELEMENT ANALYSIS

Abstract

This article presents the results of a study on the modeling and static analysis of a type of automobile wheel rim structure using the finite element analysis (FEA) method. Five different materials were used in this structure, including AISI 1020 steel, AA7075 aluminum alloy, AZ91 magnesium alloy, Ti-6Al-4V titanium alloy, and carbon fiber-reinforced composite. The analysis results showed that AISI 1020 steel had the highest mass of 27.92 kg. The magnesium alloy AZ91 had the largest displacement and the lowest Factor of Safety (FOS) values, which corresponded to 1.495 mm and 2.55, respectively. On the other hand, the carbon fiber-reinforced composite had the lowest mass and deformation values, corresponding to 6.36 kg and 0.234 mm, respectively, while achieving the highest safety factor of 37.4. However, it should be noted that this material can easily crack or fracture under severe impact and is difficult to repair once damaged. The findings of this study provide information for selecting suitable materials for automobile wheel rims, serving as a reference for improving the performance and durability of wheel rims during operation and ensuring user safety.
