Evaluation Of The Efficiency Of Diesel Locomotives On The Section Of Marokand - Kattakurgan Of Uzbek Railway, Oleg Sergeyevich Ablyalimov, Jasur Djura Ug'li Khodjiyev
Evaluation Of The Efficiency Of Diesel Locomotives On The Section Of Marokand - Kattakurgan Of Uzbek Railway, Oleg Sergeyevich Ablyalimov, Jasur Djura Ug'li Khodjiyev
Journal of Tashkent Institute of Railway Engineers
A comparative analysis of the efficiency of using diesel traction locomotives in the Marokand - Kattakurgan section of the Uzbek Railway for freight trains with and without stops at intermediate stations, siding and separate points is given. Mathematical models of conducting freight trains by diesel-powered locomotives were developed, specific resultant forces of the train were calculated and built in the modes of traction, idling and braking, curves of the speed of movement and time of the train on the considered real railway section. The kinematic parameters of the movement of freight trains and the main energy indicators of the transportation …

Calculation Of Hanging Shells Complex Geometry, Sayidmahsud Razzakov, Gennady Fridman, Rasul Khuzhakulov
Journal of Tashkent Institute of Railway Engineers
A method for calculating large-span, spatial hanging shells is presented. A resolving system of equations is obtained for determining the stress-strain state of the hanging shells, the support contour, bearing and stabilizing cables
Investigation Of Way Embankment Stability On Movement Of High Speed Trains, Mirzakhid Khamitovich Miralimov, Shakhboz Ulugbekovich Normurodov
Investigation Of Way Embankment Stability On Movement Of High Speed Trains, Mirzakhid Khamitovich Miralimov, Shakhboz Ulugbekovich Normurodov
Journal of Tashkent Institute of Railway Engineers
In this paper is considered the problem related with a stressed state of railway embankments taking into account of dynamic loadings from high-speed trains. In the offered technical method is giving wave nature transmissions of dynamic loading from the passenger trains and their interaction of soil layers with various parameters. The design procedure gives a clear physical and mathematical pattern, where all formulas are in detail shown and simple for understanding. Calculation is conducted numerically in two stages. Considering from classical principles of structural mechanics, the first calculation stage of the railway structures includes deformation of the railway sleepers taking …
