Araç Parçaları Yorulma Ömürlerinin Sonlu Elemanlar Yöntemi ile Belirlenmesi.

Automobile manufacturers are under tremendous market pressure to become internationally competitive and bring out new automobile models in the shortest time po ssible as well as keeping the validation cost to a minimum. This is making them to look for advanced techniques for reducing the development time such as service load data acquisition and analysis, life prediction for design validation. In this study, A qu estionnaire, which was applied face to face on Turkish customers, was used to determine the average usage of the light commercial vehicles in Turkey. Fatigue characteristics of Turkish roads were determined by analyzing fifty different roads. This article focuses on defining the general load spectrum of Turkey roads belong to the leaf spring. Fatigue analysis and estimated lifespan of the part were calculated using Finite Element Analyses and verified by the Palmgren-Miner rule. [ABSTRACT FROM AUTHOR]
