Abstract

This paper presents about fatigue life prediction based on finite element analysis and variable amplitude loading (VAL). Parabolic spring in the vital component is 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 variable amplitude loading for the fatigue life analysis. Service loading of parabolic spring has been collected using data acquisition system. The finite element method (FEM) was performed on the spring model to observe the distribution stress and damage. The experimental works has been done in order to validate the FEM result. The main finding can be obtained when the VAL as the input, and it was combines with the FE model. The fatigue life simulation was performed and analyzed. From the results, the fatigue damage using VAL was been predicted and the result was correlated with FEM.
