Substantiation Of Technical And Economic Indicators Of Modern Technologies With The Current Maintenance Of The Subgrade Of Railways, Pardaboy Abduraximovich Begmatov, Sunnatulla Sulaymanov, Sherzod Amirkulovich Tadjibayev
Journal of Tashkent Institute of Railway Engineers
The article summarizes the results of a comparison of technical and economic indicators of existing technologies used to clean and destroy herbs and shrubs on the territory of the railway line. It was proved that the use of small means of mechanization in the performance of work included in the routing is effective.
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 …
An Example Of Calculating The Speed Of The Railway Carriage On The Accelerating Slope Of The Hump, Shukhrat Batirovich Djabbarov
An Example Of Calculating The Speed Of The Railway Carriage On The Accelerating Slope Of The Hump, Shukhrat Batirovich Djabbarov
Journal of Tashkent Institute of Railway Engineers
The paper content is based on classic provisions of mechanics (D’Alembert principle) for non-ideal communication. The authors provide with the analytical proof of that the linear acceleration of the car when it is uniformly accelerated along the descending part of the hump depends on the force that affects the car to roll down the slope of the hump, on the force of resistance of all kinds, on the adjusted weight of the car with load taking into account the moment of flywheel action. At the same time, the results of calculations prove that the rotating parts weight practically does not …
