Reliability model of freight bogie damper based on real field data

Abstract

In the present paper is estimated the reliability probabilistic model of the dry friction damper of the freight bogie Y25. The analysis is made on the basis of real field data, observed in actual operations of freight wagons. The theoretical probability distributions used to model the reliability are exponential and Weibull. The Weibull reliability models are estimated according to the Regression Method and to the Maximum Likelihood Method.
