Remaining Useful Life Estimation of Railway Wheels Using a Gamma Stochastic Degradation Model

Sabah Louragli, Bouchra Abouelanouar, Abdeslam Lachhab

Short summary

A Gamma stochastic degradation model applied to flange width (Fw), flange height (Fh), and flange-gradient dimension (qR) of 80 railway wheels estimates median Remaining Useful Life (RUL) as 21.2–22.0 months (Fw), 13.7–17.6 months (Fh), and 5.7–9.5 months (qR).
