CONSTRUCTION OF A PROBABILISTIC MODEL OF AXLE BOX RELIABILITY
Abstract
In operation freight car axle box is subject to considerable dynamic forces that determine its relatively low durability and, as a consequence, a rapid transition to a latent state of emergency. The method for constructing a probabilistic model of axle box reliability allows to determine a moment of axle box transition in the state of failure and to prevent the emergence of a number of negative consequences for cars being on the line: derailment, train accidents, unproductive idle hours of cars, etc. The article found out that distribution law used by the author when checking the axle box life length to failure does not contradict experimental data and performed calculations.
