Development of a Calculation Method for Determining the Permissible Dimensions of the Defect 11

Abstract

This article deals with the issue of derailment of the wheels in railway transport, due to the probabilities of the wheel rolling on the rail. We proposes a method for calculating the maximum allowable sizes of defects 11, at different angles of the wheel on the rail with different shapes and sizes of wear of the wheel and rail edges. This technique allows us to calculate the permissible dimensions of Defects 11, according to the conditions of rolling the wheel crest onto the rail with the most unfavorable combination of interacting parts.
