Remaining lifetime forecasting based on the dynamic simulation of used continuously welded rails

Abstract

One of the basic principles of the modern track facilities policy is the maximum life extension of the permanent way elements less than 1,1 bln. tonnage. This policy allows to increase the competitiveness of the railway transport. The article is devoted to the research of the dynamic load impact on the target remaining lifetime of a continuously welded rail. The article also contains the results of the research that describe how some rail segments work under the load of different types, including pre-stress that develops under fastening the rail in the track and under the accumulation of the residual stress in operation.
