Abstract

Multi-leaf and parabolic spring is one of the important components in automobile. This type of spring has different design and material apply to them, but had been used for the same vehicle. The objective of this study is to analyze and evaluate the capability of parabolic spring to replace the multi leaf in suspension system. Finite element analysis had been performed to analyze the stress distribution and behavior both type of springs. Then, time histories service loading data was analyze and damage area was simulated to predict the fatigue life of the components. Finally, comparison between simulation and experimental result had been made for validating purpose. Multi leaf can hold much more load then parabolic spring, but in terms of material usage and space requirement, parabolic spring has the advantages. Stress distribution patent for both spring was vary, where for multi-leaf, the stress was concentrated at the center part, while for parabolic, stress was distributed well at the both side of the part. The outcome from the study hopefully will help in further work on development of suspension system.
