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 Jun 2020

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 Jun 2020

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 Mar 2020

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 …


To The Calculation Of Solid-State Cargo Attachment Under The Influence Of Longitudinal Forces, Khabibulla Turanov, Yadgor Ruzmetov, Jamol Shihnazarov Dec 2019

To The Calculation Of Solid-State Cargo Attachment Under The Influence Of Longitudinal Forces, Khabibulla Turanov, Yadgor Ruzmetov, Jamol Shihnazarov

Journal of Tashkent Institute of Railway Engineers

The article is devoted to the calculation of cargo fastening using the current method. It is proved that according to the existing method, the force in all elastic cargo mounts of both one and the other direction under the influence of longitudinal forces has the same value, regardless of the different location of the geometric parameters of the mounts in space. Calculations of forces in elastic elements of fastening by the specified method are given. The results of the comparative analysis showed that the forces in all wire fasteners, in contrast to the existing method of calculation, have different values. …


On The Dynamics Of The Movement Carriage In The Accelerating Grable The Marshalling Yard, Shukhrat Umarkhodjaevich Saidivaliev, Zakhro Valijanovna Ergasheva Dec 2019

On The Dynamics Of The Movement Carriage In The Accelerating Grable The Marshalling Yard, Shukhrat Umarkhodjaevich Saidivaliev, Zakhro Valijanovna Ergasheva

Journal of Tashkent Institute of Railway Engineers

The article presents the results of studies of the movement of the carriage on the slope hump (including brake position) when exposed to the forces of wind. Maintaining acceptable speed impacts and screening the Park can be achieved by changing the profiles of individual sections of the drain side hump or application of additional wagon retarders.


Plots Of Pojected Sorting Selection Hill’S The Uncertainty In The Formulas Of The Peak Constructive And Technological, Shuxrat Umarxodjayevich Saidivaliev Nov 2019

Plots Of Pojected Sorting Selection Hill’S The Uncertainty In The Formulas Of The Peak Constructive And Technological, Shuxrat Umarxodjayevich Saidivaliev

Journal of Tashkent Institute of Railway Engineers

In the article, on the basis of theorems on the change of kinetic energy for a non-free material point in the final form of theoretical mechanics, formulas for determining the braking path of the car in the braking zone of the sorting hill are derived. With a known value of the acceleration during the braking of the car the path of the car braking section can also be determined by the formula of the path of elementary physics. In the article on the basis of the theorem on the change of kinetic energy for a non-free material point in the …
