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 …

To The Conclusion Of The Variational Equation Of Motion Of Shell Structures Supported By Frames And Stringers, Farkhod Erkinovich Abdukadirov
Journal of Tashkent Institute of Railway Engineers
In this article is given the construction of the variational equation of motion of the shell structure supported by frames and stringers. Using the Hamilton - Ostrogradsky variational principle, systems of differential equations of motion of shell elements are obtained.
