Remaining life of main frame and extension of service life of shunting Locomotives on railways of Republic of Uzbekistan

Abstract

The article is devoted to topical issues of control and calculation of the residual life of the main frame of shunting diesel locomotives operated on the railway of Uzbekistan. The article presents mathematical methods for calculating the residual life of locomotives. Also, it substantiates the expediency of extending the service life of shunting locomotives at the earliest stage of their development. The results were obtained with the help of the Solid works software environment, which allows you to analyze the calculations and identify the forces acting on the main frame of the locomotives. In addition, the 3-D model of the main frame was analyzed with effort. An analysis of the locomotive fleet of Uzbekistan Temir Yo'llari JSC was carried out; based on the fleet data, a detailed analysis of shunting locomotives was carried out. Methods for predicting the main frame's residual life and extending the shunting locomotives' service life have been studied.
