Abstract

Rims are essential safety components for support, steering, mobility and break systems in automobile. Aluminum alloy rims are commonly used in the automobile industry due to their durability, light weight, high strength, good heat conductor, wear resistance and aesthetics characteristics. However, their structural integrity under diverse operating conditions is not well understood. In this study, the combined effects of static loads due to varying automobile weights and tyre air inflation pressures on the total displacement, von Mises stress and principal strain of an aluminum alloy automobile rim (Toyota 6.0JX15H2ET, CMS190CN604) was investigated using a commercially available 3-dimensional finite element code in FEMLAB® 3.0. The effects of the loading condition were investigated at the point of contact of tyre with the ground; outboard and inboard bead seats; and the well. Results showed that maximum deflection occurred at the inboard bead seat, while the most stressed area occurred at the well. Increase in automobile weight and tyre inflation pressure led to increased state of stress and strain. This study provides basic insights into the state of stress in aluminum alloy rims under diverse loading conditions.
