Abstract
this study presents a fatigue life prediction based on finite element analysis under non constant amplitude proportional loading. Parabolic spring is the vital component in a vehicle suspension system, commonly used in trucks. It needs to have excellent fatigue life and recently, manufacturers rely on constant loading fatigue data. The objective of this study is to simulate the non-constant amplitude proportional loading for the fatigue life analysis. The finite element method (FEM) was performed on the spring model to observe the distribution of stress and damage. The fatigue life simulation was performed and analyzed for materials SAE1045-450-QT, SAE1045-595-QT, and SAE5160-825-QT. when using the loading sequences is predominantly tensile in the nature; the life of mounting in Goodman approach is more conservative.
