Forecasting the residual service life of the main frame and extending the service life of shunting locomotives JSC “UTY”

The article is devoted to topical issues of control and calculation of residual life of the main frame of shunting locomotives operated on the railroad of Uzbekistan. Mathematical methods for calculating the residual life of locomotives are presented in the article and the expediency of extending the service life of shunting locomotives at the earliest stage of their development is substantiated. The outcomes were obtained with the help of the Solid works software environment which allows analyzing calculations and revealing forces acting on the main frame of locomotives. The mathematical description of forces acting during the main frame of locomotives is also presented. The analysis of the technical condition of the JSC “Uzbekistan Temir Yullari” locomotive fleet is conducted. The methods of main frame residual life forecasting and service life extension of shunting locomotives are investigated.
