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 …


About Movements Of The Carriage On The Profile Hump In A Gravity Yard, Sh.B. Djabbarov Aug 2019

About Movements Of The Carriage On The Profile Hump In A Gravity Yard, Sh.B. Djabbarov

Journal of Tashkent Institute of Railway Engineers

The article noted that in the existing methods of calculation of hump in a gravity yards the speed of the car at the braking position is determined by the formula speed of free fall of bodies given the inertia in the rotating parts of the car. Thus assume that in areas of deceleration occur rotation of the wheels of the car, that is incorrect. In it mathematical expressions and examples of calculations proved that the high-speed sections slides occur the rolling of the wheels of wheel pairs without slipping.


To The Movement Of The Car On The Site Of The First Brake Hump Yard Of Positions, Sh.U. Saidivaliyev Aug 2019

To The Movement Of The Car On The Site Of The First Brake Hump Yard Of Positions, Sh.U. Saidivaliyev

Journal of Tashkent Institute of Railway Engineers

In the article using the analytical formulas derived from the application of the basic law of dynamics for non-ideal connections (Dalembert principle), the kinematic parameters of the car’s motion (acceleration, time, braking path) were calculated in the deceleration zone at the site of the first brake position of the hump yard
