Abstract

Bir ürünün ve onun alt parçalarının gerçek çalışma koşullarındaki karşılaşabileceği yük bilgilerini kestirmek kritiktir. Bir araç parçalarının bütün hayatını tahmin etme müşteri kullanım bilgisini ve o pazarın gerektirdiği güvenilirlik bilgilerini de göz önüne alan fiziksel testler ve nümerik analizlerle saptanmalıdır. Bu çalışmada bir hafif ticari aracın Türkiye’deki ortalama müşteri araç kullanımının tespiti bir anket yapılarak belirlenmiştir. Türkiye yolların yorulma karakteristikleri 50 adet yol verilerinin incelenmesiyle saptanmıştır. Bu makale bir yaprak yaya ait Türkiye genel yol spektrumunun tespit edilmesinde odaklanmıştır. Parçanın yorulma analizleri ve öngörülen ömür hesapları, sonlu elemanlar analizleri kullanılarak hesaplanmış ve Palmgren-Miner metoduyla doğrulanmıştır

Vehicle component fatigue life definition based on the finite element method according to a customer usage profile

Abstract

Knowledge of operational loading conditions is critical when estimating the service life of a product and its components. Predictions regarding the life span of a vehicle component must be determined by physical tests and numerical analyses that take into account customer usage and market based reliability requirements. In this study, A questionnaire 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 Plamgren-Miner rule
