ANALYSIS OF RELIABILITY OF AXLE BOX BEARING UNITS OF FREIGHT CARS
Abstract
The authors present an analysis of reliability of axle boxes. Provided data characterize its level in relation to the total freight car fleet. The estimation of parameters of failure flow due to damage to roller axle boxes in cars of total fleet compared with universal covered car fleet is given. The question arises on causes of failures and possibility of having a mathematical model that could help in determining the reliability degree of axle boxes.
