ABSTRACT


This study presents fatigue life prediction under fully reversed loading. Tires are the most important part for any vehicle.  The rim is the outer edge of a wheel, holding the tire. It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles. Present rims are manufacturing using aluminium alloys. The proposed study replaces the magnesium alloys with aluminium alloys because magnesium alloys will have high impact and fatigue strength so that they can with stand vibrations and shock loading better compared to aluminium alloys. The objective of this study is to simulate the fully reversed loading for the fatigue life analysis for heavy vehicle truck wheel rim. The finite element method (FEM) was performed on the rim model to observe the distribution of stress and damage. The fatigue life simulation was performed and analyzed for materials Al alloy (Al35T6 recent material for forged wheels) with ALMG alloys (AL6082, AL6060). When using the loading sequences is predominantly tensile in the nature; the life of mounting in Goodman approach is more conservative. When the loading is predominantly tensile in nature, the life of the component in Morrow approach is more sensitive and is therefore recommended. It can be concluded that material AL6082 gives constantly higher life than other material for given loading condition.


Keywords: Fatigue life; fully reversed loading; heavy truck wheel rim; total-life; crack- initiation; FEM.
