A New Approach for Reliability Life Prediction of Rail Vehicle Axle by Considering Vibration Measurement

Abstract: The effect of vibration on the axle has been considered. Vibration measurements at different speeds have been performed on the axle of a running rail vehicle to figure out displacement, acceleration, time, and frequency response. Based on the experimental works, equivalent stress has been used to find out life of the axles for 90% and 10% reliability. Calculated life values of the rail vehicle axle have been compared with the real life data and it is found that the life of a vehicle axle taking into account th… Show more

“…Moreover, the performance and fatigue life of vehicle components are influenced by any variation in vehicle axle load. 24,25,28 However, as shown in Figure 4, an empty wagon was used in the test. The characteristics of the empty test wagon were imported in the model to perform the model validation in order to provide the same condition for numerical and experimental studies.…”

“…Bu ömür değerlendirmeleri bir çok farklı yöntemle gerçekleştirilebilmektedir. Bununla beraber yorulma faktörleri de göz önüne alınmak suretiyle Wöhler diyagramlarından elde edilen ömür denklemleri ile gerçekleştirilen hesaplar basit ve gerçekçi sonuçlar ortaya koymuştur (Meral Bayraktar et al, 2014Dikmen et al, 2012). Bu çalışmada da ömür analizleri benzer yaklaşımla gerçekleştirilmiştir.…”

“…Farklı gerilme seviyelerinden dolayı yorulma hasarının birikimi problemi bu tür parçalarda ortaya çıkar (Lemaitre, 1996). İlk kümülatif hasar teorisi, A. Palmgren tarafından 1920'de İsveç'te rulmanların ömrünü tahmin etmek için uygulanmıştır (Meral Bayraktar et al, 2014). Palmgren-Miner doğrusal hasar kuralı, dinamik gerilim genliği döngülerinin toplanması sırasında bileşenin yorulma ömrünü tahmin eder.…”
