Rin-in comb wheels of the wheel pair of the car when moving on a curve section of the path

Abstract

In the article, using the classical provisions of theoretical mechanics, various methods of constructing a computational model of rolling in the wheel crest of a wheelset of a wagon from when moving rolling stock along a curved section of track are presented.

Hardening the rolling surface of the wheels bandage after mechanical treatment

“…After experimental specification of the radial modes of strengthening the material of diesel locomotive bandages for the designed stand, on the basis of theoretical and computational studies, the technological provisions of the stand operation manual will be defined [11][12][13].…”

“…Then comes the period of uniform wear and it is about 100 thousand km. Therefore, it was necessary to find and eliminate the root causes that cause increased wear of the wheel sets bandages of locomotives and rails [11][12][13].…”

“…Increasing the speed of movement leads to the increase in dynamic loads on wheel sets, and the appearance of high-frequency vibrations in the areas with great rigidity of the track. Increasing the load from the wheel sets, maximum realized traction force and speed leads to an increase in the stress state of the rail and wheel, this in turn increases the wear of the wheels and rails [11][12][13].…”
