Abstract
The article estimates the intensity of rail failures on the sections of the Middle Siberian Railway (on the example of Kr and Km track distances). The analysis of rail failures depending on the passed tonnage, plan and profile parameters is carried out. Mathematical models of rail yield on I and II tracks depending on the missed tonnage, weighted average gradient, weighted average radius and curve share are considered.
The influence of the passed tonnage on the rail output has been determined: on I track at tonnage increase from 100 to 1400 million tons the average value of rail outputs increases from 0 to 24 pcs./km, on II track – at tonnages from 100 to 700 pcs./km the average number of rail outputs increases from 0 to 1,8 pcs./km. However, during the whole operation period there is an accelerating intensity of rail failures growth from 0,7 to 4,3 pcs./km per 100 million tons depending on the tonnage interval.
The influence of operational parameters of the plan and profile of the track of the Central Siberian mainline (the share of curves, average radius, average longitudinal slope) on rail failures has been determined. Dependence of rail failures on I track: on the share of curves – intensity of rail failures is 2,9 pcs/km on average for every 10 % of curve share. Influence of weighted average radius – when reducing the curve radius from 3 000 to 1 100 m on the example of tonnage level of 1 000 million tons, the rail output increases 3.5 times (from 4 to 14 pcs./km). Influence of weighted average gradient – when the gradient increases from 1,5 to 3 ‰ at the tonnage of 900 million tons, the rail yield increases 3 times (from 4 to 12 pcs./km).
The correlation-regression analysis of rail yields from missed tonnage and parameters of track plan and profile has been carried out.
